What is the value of π 4 in trigonometry?
The actual value of cos pi/4 is √2/2 in radical form and 0.7071 in decimal form.
How do you solve Sin pi over 4?
How to Find the Value of Sin pi/4? The 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.
