Question

find integrals of
dx/(1+3sin^2 x)

Answer 1

hint : divide numerator and denominator by cos^2 x

Answer 2

then put t=tan x

Answer 3

Found it somewhat tricky. I thought of it as factoring out a cos^2(x) from the denominator. Also get rid of the resulting csc^2(x)

Answer 4

sec^2 x dx / (sec^2 x + 3 tan^2 x) how to proceed after putting t = tanx

Answer 5

Remember sec^2(x)=1+tan^2()

Answer 6

yeah, and since t= tan x
dt = sec^2 x dx

Answer 7

yes got it thank you very much for all. Some more diff problems to come.... pls help

Answer 8

welcome and sure :)
