If `I_n=int cos^n x dx` , then `I_7-(cos^6xsinx)/7=`

int cos^(7) x dx

If I_(n) = int cos^(n) x dx , then 6I_(6) -5I_(4) =

If I_(n)=int (cos nx)/(cosx)dx, then I_(n)=

Show that If I _(n) =int cos ^(n) x dx, then show that I_(n) =1/n cos ^(n-1) x sin x + (n-1)/(n ) I_(n-2).

If I_(n)= int(sin nx)/(cos x)dx , then I_(n)=

If I_(n) = int Sec^(n) x dx then I_(8) - (6)/(7) I_(6) =

Evaluate the reduction formula for I_n = int cos^n x dx and hence find int cos^4 x dx .

If I_n = int sin^n x \ dx, then n I_n - (n-1) I_(n-2) equals
