Solve the following function $\int\limits_{ – \pi }^\pi {\sin (t)\sin (3t)dt = }$
Solve the following function $\int\limits_{ - \pi }^\pi {\sin (t)\sin (3t)dt = }$
Right Answer is: 0
SOLUTION
$\int\limits_{ – \pi }^\pi {\sin (t)\sin (3t)dt = }$
sin(t).sin(3t) Is even function therefore the limits becomes
