If `f(x)` is differentiable and `int_0^(t^2)xf(x)dx=2/5t^5,` then `f(4/(25))` equals `2/5` (b) `-5/2` `1` (d) `5/2`

If f(x) is differentiable and int_(0)^(t^2)xf(x)dx=(2)/(5)t^5 ,then 5 f((4)/(25)) is equal to ....

If f(x) is differentiable and int_(0)^(t^(2))xf(x)dx=(2)/(5)t^(5), then f((4)/(25)) equals (a)(2)/(5)(b)-(5)/(2)(c)1(d)(5)/(2)

If f(x)=f(2-x) then int_(0.5)^(1.5)xf(x)dx=

Differentiate sin(x^(2)+5) w.r.t. x.

If f is continuously differentiable function then int_(0)^(2.5) [x^2] f'(x) dx is equal to
