Document Summary
Sketch the plane curve for the following parametric equations: plug in values for t to obtain values for x and y. t. 1: plot the coordinates (x,y), draw shaded arrows in order of the increasing t values. Note: t values can either be increasing in the positive direction or t values can be increasing in the negative direction depending on those values. (-2, 8) Eliminate the parameter using the following parametric equations. (7,-4) (3,2: solve for the parameter in terms of x. x = Note: you can solve for the parameter for either variable, but solving for x is preferable because it reduces algebraic manipulation towards the end. x x t. 2 x: solve the equation in step one for y. 1(9 x: substitute the value of t into the y equation. Note: this step also works vice versa if you solved the parameter in terms of y. Eliminate the parameter using the following parametric equations.
