Evaluating Expressions - SymPy Tutorial 06

This is the sixth video in a new series on SymPy - Symbolic Computations in Python. In this video, we will show you how to substitute values in expressions. Also, we will talk about restricting symbols to be of specific types (such as real, positive, or integer).

The log is a multiple-valued function in the complex plane.

It was a 9 minute video and I didn't see an evaluation of an expression like f(x) = 2*x+3, solve this function for x (I know how to do in Python symbolically), then evaluate f(x_sol) which was the x we solved for in the previous step.

Nvm. After 5 hours I was able to write a function that does what I wanted above. Sorry
def starting_x_y_value(expr, x_start, y_start):
expr = solve(3*x+4, x)
x_start = expr[0]
y_start = 3*x_start+4
