Understanding Functions and Logarithms

The video tutorial explains how to express y as a function of x by removing the parameter T from a set of parametric equations. It starts by introducing the parametric equations x = e^T and y = T, and then demonstrates how to solve for T using natural logarithms. The tutorial proceeds with substituting T in the equation for y, resulting in y = ln(x). The video concludes with a brief overview of the necessary logarithmic properties.
