I want to integrate with respect to dt by range i mean range is for integration sign (above and below) i dont know how to write integration sign here

Kindly explain me in detail 1. $\displaystyle \int{e^{-2at}\,dt} = -\frac{1}{2a}e^{-2at} + C$ 2. I know what you mean by range, I just don't understand the limits you've given me. Is it $\displaystyle \int_{-\frac{t}{2}}^{\frac{t}{2}}{(\cos{t} + 5\cos{2t})^2\,dt}$?
Kindly explain it
