If u_(10)=int_(0)^(10)x^(10)sin xdx, then the value of u_(10)+90u_(8) is :

int x sin x sec^(3)xdx ise q u a lto

If u _(n) = int _(0) ^(pi//2) x ^(n) sin x dx, n in N then the value of u _(10) + 90 u _(s) is

If intsin^(-1)xdx=x sin^(-1)x+u+c, then u=

If u_(n) = int_(0)^(pi/2) x^(n)sinxdx , then the value of u_(10) + 90 u_(8) is : (a) 9(pi/2)^(8) (b) (pi/2)^(9) (c) 10 (pi/2)^(9) (d) 9 (pi/2)^(9)

For the sequence {u_(n)} if u_(1) = (1)/(4) and u_(n+1) = (u_(n))/(2+u_(n)) , find the value of (1)/(u_(50)) .

If u_(n) = cos^(n) alpha + sin^(n) alpha , then the value of 2 u_(6) - 3 u_(4) +1 is :
