I would multiply the integrand in fact by to get:
then use the subsiitution:
to get:
and now use partial fractions to complete the job, back-substituting for at the end.
Hi,
Can someone help me with this problem?
integral (9sec(theta))/(1+sin(theta))
WolframAlpha told me to multiply the top and bottom by -cos^2(theta), then converted it into something else using u=sin(theta)... but I don't understand. (I've reached my daily limit of free step-by-step solutions, so it won't let me view it anymore.) Is there another way to do this problem?
