int(1n)/(12(a)n-5sin x)

int(1)/(5sin x-12cos x)dx

If I_(n)=int(sin nx)/(sin x)dx, for n>1, then the value of I_(n)-I_(n-2) is

int ( n sin^(n-1))/(secx (sin x)^(n)) dx equals :

int ( n sin^(n-1))/(secx (sin x)^(n)) dx equals :

If int_(n)=int_(-pi)^(pi)(sin nx)/((1+pi^(x))sinx) dx, n=0,1,2,………. then

If I_(n) = int (sin nx)/(sin x)dx where n gt 1 , then I_(n)-I_(n-2)

Evaluate: If int cos^(n)xdxdot provethatI_(n)=(1)/(n)(cos^(n-1)x sin x)+((n-1)/(x))I_(n)

If A_(n)=int_(0)^((pi)/(2))(sin(2n-1)x)/(sin x)dx,B_(n)=int_(0)^((pi)/(2))((sin nx)/(sin x))^(2)dx for n in N, Then (A)A_(n+1)=A_(n)(B)B_(n+1)=B_(n)(C)A_(n+1)-A_(n)=B_(n+1)(D)B_(n+1)-B_(n)=A_(n+1)
