Using the period to help evaluate a trig function for an angle - free math help

👉 Learn how to evaluate trigonometric functions of a given angle. Given an angle greater than 2pi in radians, to evaluate the trigonometric functions of the given angle, we first determine the smallest positive coterminal angle of the given angle. This we can do by subtracting 2pi or a multiple of 2pi from the given angle.

Coterminal angles are angles with the same terminal side. After obtaining the coterminal angle, we plot the angle on the x-y-coordinate plane and with the help of the Pythagoras theorem or the special angles, we can evaluate the trigonometric functions of the given angle.

whoever has him for a teacher irl.... don't take it for granted because theres a reason why we're here....

The fact that I’m watching this in my math class tells me that my math teacher needs to go home and find a different job. Great video

[jordanransom]

Oh my gosh that makes so much sense now, my teacher never explains this in a way where I can understand, thank you so much!

[kelseyjohnson]

Thank you. These videos have literally saved my GPA.

[alissawinston]

You know they're a fire teacher when they just throw the expo markers around when they dont work. Passion man.

[NoraCassandraNyyssonen]

Thank you... I have spent a week trying to understand what my teacher tried explaining and my brain was refusing it... now it’s clear! Thank you 🙏

[talkintruth]

Gosh, this made it so easy to understand. Passed my midterm thanks to you!

[cesarrodriguez-twbp]

thanks a lot for uploading this ... this was so easily explained, I've been trying to understand it by reading my book but nothing. Thanks a lot!!

[kailawebb]

omg thanks! my teacher forgot to explain this before she gave us the assignment-- this saved me!

[isabellarocca]

this man has taught me more than my actual teacher

[dianajmz]

Missed class. watched your vid and I got it:) and it was short just PERFECT. thanks

[mikehenry]

Sir truly think your so smart ...you get crazy at times in a smart way..???

[bartatier]

Keep it up man, I appreciate your videos and like them all!!

[raybaca]

Thank you so much!!! I understand it!!

[brianmclogan]

awesome!, let anyone else know if they need math help, be careful I do upload a lot but it's all good stuff

[EmptySequencee]

Wow, you're awesome thanks soo much! I love your channel, its such a huge help. You just earned a new subscriber mt friend.

what happen if the denominator is not a 2 but it's a 4,

[holographicmeatloaf]

When the guy in the video does the exact problem you have for homework

[sevens]

Great explanation, but how come you started with 4pi/2?

[JoeyG]

What if the denominator is not 2 and is another number would you still use 4/2?
