The lesson was easy to understand, it was simple and straight forward. When I finished watching the video, I identified the 6 trigonometric functions and how to solve it's angles. Thank you for the wonderful video! More videos to come!

Honestly, I can't believe that I would learn easier on this topic with this video.

The video tackled trigonometric functions and quadrantal angles, as well as trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant).

It also tackled quadrantal angles and was defined as angles in standard position with terminal sides lying along either the x-axis or y-axis.

Thank you so much for the video!

Even though math isn't my strongest subject, the clarity with which the lesson was delivered in this video allowed me to not only grasp the lesson but also absorb its ideas, which has been incredibly beneficial for me in solving the lessons. With the help of this lesson, I was able to learn about the six different trigonometric functions, including sine, cosine, and cotangent, along with their reciprocals, the cosecant, secant, and tangent. I also learned how to evaluate and solve for the trigonometric function values of an angle. I'm grateful for the video and eagerly awaiting more instructive videos like this in the future!

I enjoy the fact that Ma’am uploads her lessons and allows us to rewatch it. Her teaching allows me to learn these topics easier than I’d imagine! Trigonometry looked very intimidating for me, however, now with this I can take my own time to learn step by step. 🥰

This video gives a clear explanation on trigonometric functions and how to apply them to quadrantal angles as shown in the examples. What was also discussed was the six trigonometric functions are as follows: sine, cosine, secant, cosecant, tangent, and cotangent, as well as how they relate to each other (reciprocals). The table shown at the end is also very helpful in simplifying the previous information that was discussed which was undefined function values.

Thank you for the wonderful video!

[solonjashleynoraine]

The lesson was articulately delivered which helped me learn more in Mathematics! By the end of this lecture video, I am now able to solve function values of an angle, define quadrantal angles, and evaluate the trigonometric function values of quadrantal angles. Thank you for making video like these which help us students learn and understand more about Mathematics! 🌻

[tejoneskykiskec.]

Excellent video! It is articulate and easy to comprehend, I am now able to solve for functions of values of an angle and define what are quadrant angles. I find this channel to be extremely helpful and educational- thank you so much!

At first, I was scared to learn the SOHCAHTOA because from what I hear, people find it very difficult. But with this video, I can say that I truly understand the basis of the six Trigonomental functions namely, sine(sin), cosine(cos), tangent(tan), and their reciprocals, cosecant(cos), secant(sec), and coterminal(cot), respectively. Furthermore, I also learned about the Quadrantal angles which are angles in standard position with the terminal side lying on either the x-axis or the y-axis. With this, it is certain that two of the 6 trigonometric functions, would be undefined. I’m looking forward to our next lessons tackling trigonometric functions because I already understood it from this helpful video.

In this video, I learned about the six different trigonometric functions. These are the sine, cosine, and cotangent with their reciprocals, namely, the cosecant, secant, and cotangent. Thank you, ma'am Didith, for this informative lecture, for I have learned how to solve and evaluate the trigonometric function values of an angle. I'm looking forward to more of your lecture videos!

The video lesson tackled trigonometric functions (sine, cosine, tangent, cosecant, secant, cotangent) and their relation, and quadrantal angles (angles in standard position with terminal sidee lie along either x-axis or y-axis). The explanation was clear and concise and every topic was discussed properly. If you are struggling to understand trigonometric functions, then this is the video for you.

[kevintalan]

In this lesson, we got introduced to the trigonometric functions especially the angles: sine, cosine, tangent, cotangent, secant, cosecant as well as the SOHCAHTOA. I’ve noticed that they’re the reciprocal of each other. This video serves a lesson for those students who are finding trigonometric functions hard. Thank you for the video!

This video lecture helped me to understand this topic. It is really clear and easy to comprehend. I look forward to more lessons like this. 😊

[francescaangaleddicot]

I already heard the terms - sine, cosine, tangent, cotangent, cosecant, and secant before. I always notice these terms too whenever I am using a calculator. To tell the truth, seeing them is kind of scary to me, because it gave me the thought that it is not easy to learn and understand. But a big thanks to this video because learning these - Trigonometric Functions became easy for me and the other viewers too. It also gave me knowledge about the Quadrantal angle - an angle whose terminal side is on the x-axis or y-axis, and also taught me how to find the function values of an angle.

Hoping for more tutorial videos like this!❤

[aganonandrealeigha.]

This video is really great! It explained properly about the Trigonometric Functions - which I'm struggling to learn about until I watched this video - and it greatly helped me to understand the lesson in a much easier way. I didn't know that if we just remember the rules of SOHCAHTOA and how we can solve for r, we can already solve for the Trigonometric beginner-level questions! It was also fun learning this topic while watching this video as it explains properly how each are related to the other and how we can understand the lesson better if we know the terms used in solving this kind of equations, such as quadrantal angles, adjacent hypotenuse, the meaning of SOHCAHTOA, etc., and also the simple rules, such as the reciprocals of the sine, cosine, tangent, cotangent, secant, and cosecant. I'm really grateful that you made this video, Ma'am. It helps me a lot in studying for my Trigonometric Functions test as everything was explained and taught articulately. I'm hoping to learn more in your future videos po! ^^

Thanks to the video, I was able to quickly learn about trigonometric functions and quadrantal angles. The teacher was concise and comprehensive with the discussion, making the lesson easier for me to digest. At first, I was nervous opening the video as trigonometry had always been an unfamiliar concept for me, yet thanks to this video, I was able to easily learn and understand more about this area of mathematics.

This math video was incredibly helpful! The way the concepts were explained and demonstrated made it much easier for me to understand and retain the information. I appreciate the clear and concise explanations, as well as the helpful examples and practice problems. Thank you for creating such a valuable resource.

Honestly, it's been so long since I fully understood a math topic. But with the help of you providing us these videos, I comprehended it with ease. It was taught slowly, which made it easier for me to grasp every detail of the lesson. Also, I like how cohesive you are when you teach; it helps me make vital connections across concepts. Thank you, ma'am!

I am so glad that the video lecture clearly explained the Trigonometric Functions and Function Values as it helped me so much. SOHCAHTOA also helped us in solving Trigonometric functions easier. Finding function values of Quadrantal angles was also tackled, the lecture video also showed us a table for commonly used Quadrantal Angles which help us in solving faster.

The lecture video helped me understand the six trigonometric functions: sine (sin), cosine (cos), tangent (tan), and their reciprocals, cosecant (csc), secant (sec), and cotangent (cot). The acronym SOHCAHTOA is also very helpful because it makes the trigonometric functions easier to remember and solve: SOH stands for Sine (sin) = Opposite/Hypotenuse, CAH stands for Cosine (cos) = Adjacent/Hypotenuse, and TOA stands for Tangent = Opposite/Adjacent. Finally, I learned about quadrantal angles (angles in standard position whose terminal ray lies along one of the axes); the lecture video is simple to follow because each topic is covered thoroughly and concisely.

Trigonometric function is such a topic I am afraid to encounter in math, I am so bamboozled by sine, cosine, tangent and such. But through this video, I have learned how to find the function values of an angle and the concept of quadrantal angles. I think something that I won't forget in this lesson would be the SOH-CAH-TOA, it really made easy the process of finding their values.
