Example 37
Evaluate
Solution : Let cos x = t
then -sin x dx = dt
\ sin x dx = -dt
Example 38
Evaluate
Solution : Let x2 = t
then 2x dx = dt
Again put sint t = u, then cos t dt = du
Example 39
Evaluate
Solution : Let 1 + x2 = t
then 2x dx = dt
\ x dx = ˝ dt
Example 40
Evaluate
Solution :
Example 41
Evaluate
Solution :
Let cos x + sin x = t then (-sin x + cos x) dx = dt
