Expand the Trigonometric Expression pi/4

Problem

π/4

Solution

1. Identify the expression provided. The expression is a constant value representing an angle in radians.

2. Determine if expansion is possible. In trigonometry, "expand" usually refers to applying identities to functions of sums or differences, such as sin(A+B) Since π/4 is a single constant value and not a function of an algebraic expression, it cannot be expanded further in a trigonometric sense.

3. Evaluate the trigonometric context. If this value is intended as an argument for trigonometric functions, it corresponds to 45

Final Answer

π/4=π/4
