Given a point P (x, y) on … WebDec 20, 2024 · However, just as we did with the original trigonometric functions, we can give exact values for the inverse functions when we are using the special angles, specifically π 6 (or 30°), π 4 (or 45°), and π 3 (or 60°), and their reflections into other quadrants. Given a “special” input value, evaluate an inverse trigonometric function.

How do you use the reference angles to find #sin210cos330-tan 135#? How do you know if #sin 30 = sin 150#? Web150° is located in the second quadrant. The angle it makes with the x -axis is 180° − 150° = 30°, so the reference angle is 30°.This tells us that 150° has the same sine and cosine values as 30°, except for the sign. We know that. cos ( 3 0 ∘) = 3 2 a n d sin ( 3 0 ∘) = 1 2. built-in bed ideas
