Evaluate
first divide nominator by denominator –
: To solve this type of solution ,we are going to substitute the value of sinx and cosx in terms of tan(x/2)
In this type of equations we apply substitution method so that equation may be solve in simple way
Let tan(x/2)=t
1/2.sec2(x/2)dx=dt
Put these terms in above equation,we get
Substitute these terms in above equation gives-
Now put the value of t, t=tan(x/2) in above equation gives us the finally solution
