    Cauchy integral theorem question

    I think you are just confused about the Cauchy-Goursat Theorem, it is a one sided implication which states that the integral of an analytic function over a closed contour is 0, but the converse is not generally true. You actually don't need a simply connected region to apply Morera's Theorem...

    How Do You Solve the Infinite Integral in Quantum Mechanics Demystified?

    It will basically work if you know how to switch to polar cordinates.

    Fairly basic trigonometric equation

    How about A=Pi/2 B=3Pi/2

    Limit as x-> 4 of 3-x / x^2-2x-8

    since as X -> 4- the numerator will go to -1 and the denominator will go to 0- because x is just a little less than 4 the fraction -1/0- (when 0 is on the left side of the real axis and really close to 0) will give you infinity

    To find logarithm of a complex number

    I remember something like Ln(z) = Ln(|z|) + iArg(z) where |z| is the amplitude and arg(z) is the angle in radians between the point z and x axis.
