Parametrization is a technique in calculus for expressing multiple variables in terms of only one variable, which is usually depicted as "t", over a specified range.
The most common parametrization is for a circle centered at the origin in the xy-plane:
- <math>x=r \cos(t)</math>
- <math>y=r \sin(t)</math>
- <math>z=0</math>
- <math>0 \le t \le \pi</math>
Always remember to be precise in determining the new limits on the new parameter t.
This technique is particularly useful for calculating extrema and line integrals.
