WebJan 2, 2024 · Finding the exact value of the sine, cosine, or tangent of an angle is often easier if we can rewrite the given angle in terms of two angles that have known trigonometric values. We can use the special angles, which we can review in the unit circle shown in Figure . Figure : The Unit Circle WebThe value of sin pi/4 can be calculated by constructing an angle of π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (0.7071, 0.7071) on the unit circle. The value of sin pi/4 is equal to the y-coordinate (0.7071). ∴ sin pi/4 = 0.7071. Download FREE Study Materials Trigonometry Trigonometry Worksheet Explore
