Final answer:
To solve the trigonometric equation in radians, substitute the given values into the equation and check for values that satisfy it.
Step-by-step explanation:
To solve the given trigonometric equation in radians, we need to find the values of the variable that satisfy the equation. In this case, the equation is not provided, but we are given a list of possible values for the variable, represented in radians: a) π/4, b) 3π/4, c) 5π/4, d) 7π/4.
To solve the equation, you would substitute each of these values into the equation and check if it satisfies the equation. If any of the values make the equation true, then that value is a solution to the equation.
