Write parametric equations in rectangular form by eliminating the parameter.

x=2t²

y = 3t - 4

y=3(sqrt.(x/2)) - 4

500

Sketch the curve represented by these parametric equations.

x = t² - 6

y = (1/2)t - 1

Converting Equations

100

What is the difference between polar and rectangular equations?

Polar uses a radius and an angle

Rectangular uses x and y

200

Write the 4 equations we use to convert between polar and rectangular equations.

1

2

3

4

300

Convert the rectangular equation to polar.

Remember, get r alone.

x = 8

r = 8/cos0

or

r=8sec0

400

Convert polar to rectangular

r = 4sin0

x² + y² - 4y = 0

500

Convert to polar form.

x = y²

r = cot0csc0
