Hello I need help with 2 problems.

The first is

Code:F(x)= Integral from sqrt(x) to 2 (tan(t)/t^2) dt Find F'(x)

The second is

Code:Find the actual area under the curve f(x)=2x^2 on the interval [0,3]. Use right hand endpoints and the formula Area = lim n→ ∞ n Σ i=1 f(x^*i) delta(x)

Here is an image of the equations
