Step 2 - After reaching a peak, the voltage starts dropping. The capacitor must discharge now, so the current reverses direction. When the voltage passes through zero at point c, it's changing quite rapidly; to match this voltage the current must be large and negative. Step 3 - Between points c and d, the voltage is negative.

Python Sympy is a package that has symbolic math functions. A few of the notable ones that are useful for this material are the Laplace transform (laplace_transform), inverse Laplace transform (inverse_laplace_transform), partial fraction expansion (apart), polynomial expansion (expand), and polynomial roots (roots). For example, take the function y=f(x)=x^2. For any given x, there is a y that is equal to x^2. The derivative of this function happens to be f1(x)=2x, meaning that for a given point on the original curve, its slope can be represented by 2x. So, at x=4, f(x)=4^2=16, and its slope at that point, f1(x)=2(4)=8, or 8 units up for every 1 unit over. Drupal-Biblio 17 ...
