(a)  Evaluate the integral of the function:  y(x) = ((3x + 1)/(2x^2  − 2x + 3))  (b)   Find the constant A, B, C in the identity:                               ((3x^2  − ax)/((x − 2a)(x^2  + a^2 ))) ≡ (A/((x − 2a))) + ((Bx + Ca)/((x^2  + a^2 )))  where  a  is a constant,  hence prove that.                                               ∫_0 ^( 2)   ((3x^2  − ax)/((x − 2a)(x^2  + a^2 ))) dx = (π/4) − (3/2) ln(2)
