Question

Evaluate ∫₀^π sin³(t) dt
Options
A 1/2
B -1/2
C 4/3
Correct Answer
D -4/3
Correct Answer

Option C is the correct answer.

Detailed Explanation

Write sin³t = sin t(1-cos²t) and substitute u=cos t. This gives ∫₀^π sin³t dt = 4/3.

Hint

Split off one sine factor and use u=cos t for the remaining sin²t·(-du) piece.
