" (v) "(u sin u+cos u)/(u^(2)log u)

Differentiate the following functions w.r.t. t : (u sin u+cos u)/(u^(2)log u)

if int e^(2x)sin x cos xdx=(u)/(8)e^(2x)+c then u

A body is projected obliquely from the ground with a speed 'u' and at an angle "'theta with the horizontal.It's velocity at the maximum height is (A) zero (B) u sin theta,(C) u cos theta (D) u

If u_(n) = sin ^(n) theta + cos ^(n) theta, then 2 u_(6) -3 u_(4) is equal to

If u_(1), u_(2), u_(3),… form a G.P. with common ratio k, find the sum of u_(1)u_(2) + u_(2)u_(3)+….+u_(n)u_(n+1) in terms of u_(1) and k.

If quad tan((1)/(2)(cos^(-1))(1-u^(2))/(1+u^(2))+(1)/(2)(sin^(-1))(2u)/(1+u^(2))) and x=(2u)/(1-u^(2)) then (dy)/(dx)

If y=tan[(1)/(2)cos^-1((1-u^(2))/(1+u^(2)))+(1)/(2)sin^(-1)((2u)/(1+u^(2)))]" and "x=(2u)/(1-u^(2))," then: "(dy)/(dx)=

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)) .
