Missed the previous lesson?

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Cant believe how easy this stuff is now that I actually understand it, my foreign teacher has a hard time explaining things lol

3:42 For those curious, the positive slope is 3π, and the negative slope is -3π. (In terms of tau, those are 3τ/2 and -3τ/2, respectively.) Knowing that the graph is y = 3sin(πx) + 1, these slopes can be found using calculus.

thank you so much for the help. This makes a lot more sense now

finding the period doesn’t make sense to me 😩

I am recently learning about periodic function, this may give me a better understanding.

How would you find the midline if you didn’t have a picture?

does the midline always have to be either -1 or 1?

one thing i would like to see how actually f(x+1)=f(x)=f(x-1) being expressed on a fiction, because in this equation i see but three unconnected graphs

Can the period be represented by time rather than angle eg: 2Pi/b = 2Pi for sin(theta)

If expressed as time is 2Pi=360degrees=12hours? then 30degrees would be 1 hour and so on?

How do you know if you need to add or subtract? Confused
