Multiplying trigonometric expressions
WebIn this section, we discuss some ways that we can perform advanced manipulation of expressions. Understanding Expression Trees# Before we can do this, we need to understand how expressions are represented in SymPy. A mathematical expression is represented as a tree. Let us take the expression \(x^2 + xy\), i.e., x**2 + x*y.
