This study guide covers parametric functions, including their definition as x = f(t) and y = g(t), their use in representing complex shapes and motion, and how they work. It emphasizes key concepts such as the parameter t, parametric representation f(t) = (x(t), y(t)), creating a table of values for graphing, and the impact of domain restrictions on start/end points. The guide also includes practice questions and exam tips covering parametric equations of circles and ellipses, graphing, domain restrictions, and applications.

Question 1 of 12
In parametric equations, what is the role of the parameter 't' 🤔?
It directly relates x and y coordinates
It's a constant value that doesn't change
It is used to define both x and y coordinates
It represents the slope of the curve
