# U-Substitution, Integration by Parts and Differential Equations (8 Problems)

Please show all of the steps needed to solve the 8 integrals and differential equations that are attached.

The integral of x(cos(x) dx

The integral of (x^3) sin(x) dx

The integral of t(csc(t))cot(t) dt

The integral of arctan x dx

The integral of e^2x sin(X) dx

Solve the differential equation.

y' = xe^x2

dy/dt = y^2/sqrt(2 + 3t)

cos(y) * y' = 2x.
