Write as a Function of x x=pi/4

Problem

sin(π/4)

Solution

1. Identify the trigonometric function and the given angle x=π/4

2. Recall the coordinates on the unit circle for the angle π/4 radians, which corresponds to 45^∘

3. Determine the value of the sine function, which represents the ycoordinate at that point on the unit circle.

4. Evaluate the expression using the known exact value.

Final Answer

sin(π/4)=√(,2)/2
