Expert Answer:

begin mathsize 16px style In space the space integration space we space always space put space angle space as space straight t.
Put space straight e to the power of negative straight x end exponent equals straight t space rightwards double arrow space minus straight e to the power of negative straight x end exponent dx equals dt space

And space solve space using space formula space for space sin squared straight theta equals fraction numerator 1 minus cos 2 straight theta over denominator 2 end fraction


NOTE colon space Please space check space the space question space again space as space if space you space try space to space solve
using space straight e to the power of straight x space then space integration space will space repeat. space Hence comma space straight e to the power of negative straight x end exponent space should space be space there space
instead space of space straight e to the power of straight x.
end style
