can anyone do these calculus problems

[moddy]

problem 1.

The expression f(t)=10t^2 x sin(2t) represents the work done in kJ by a mechanism on a canning plant against time. By using the process of integration, determine the power dissipated between 1 and 1.3 seconds after the device starts to function.

By the way, f(t)=10t^2 x sin(2t), with the ^ means to the power of 2. Just cant put the equation in correctly as its an e-mail.

Problem 2.

The function Ln((5t^3 - 6t)^3) represents the position of a lever on a mechanism at some point in time. Differentiate the function to determine its velocity 3 seconds after it starts to move.
