Q20 of 45 Page 1

Find :

We have to find the integral of but first we will convert this trigonometric function into algebraic function by substitution which is,

Put cos θ = x, so,


= - sin θ, so,


dx = - sinθ dθ, hence our function is now,




We will solve this function by factorizing the numerator to form the terms same as the denominator.



Putting this value in the function,
