trans(e, t, x, y)

• e is an equation in terms of x and y
• t is a matrix transformation of x and y
• x and y are variable names

Returns the equation after the transformation is applied.

Example

\(f(x) = e^x + e^{-x}\) and \(g(x) = \dfrac{1}{2} f(2-x)\). Find a possible sequence of transformations that map \(f\) to \(g\). (2023 Methods Exam 2 Section B Question 5a)
