Parametric and Polar for BC

Front

What are parametric equations?

Back

Parametric equations express the coordinates of points on a curve as functions of a variable, typically denoted as 't'. For example, x = f(t) and y = g(t).

How do you find a point from parametric equations?

Back

To find a point from parametric equations, substitute the given value of 't' into the equations for x and y. For example, if x = 1 - 2t and y = 4t + 1, for t = 3, x = 1 - 2(3) = -5 and y = 4(3) + 1 = 13, giving the point (-5, 13).
