Identify two errors made by a student asked to evaluate the following integral (Will upload question to less space)
Error 1: expressed 3/x^(1/2) incorrectly. Should be 3x^-(1/2), not 3x^(1/2).Error 2: subtracted the larger area from the smaller area after substituting the unknowns with the given limits value.

Via the product rule, or otherwise, differentiate 'y = xsin(x)'.
Let f(x) = 5x^4 + 6x^3 + 3, find dy/dx at x = 3
Solve 4cos(2x )+ 2sin(2x) = 1 given -90° < x < 90°. Write 4cos(2x )+ 2sin(2x) in the form Rcos(2x - a), where R and a are constants.
