RTT - Sine and Cosine Lesson
Sine and Cosine
Trigonometric functions express ratios of the sides of a triangle relative to its angles. There are six trigonometric functions - sine, cosine, tangent, secant, cosecant, and cotangent. We are going to take a closer look at the "big three": sine, cosine, and tangent. Check out the video below to learn more!
There is a special relationship between the sine and cosine of complementary angles. Learn about it below:
