Question

How do you convert the polar equation `theta=30^o` into rectangular form?

Answer 1

Use the tangent function on both sides.
Substitute `y/x` for `tan(theta)`
Multiply both sides by x

Explanation:

Use the tangent function on both sides:

`tan(theta) = tan(30^@)`

Substitute `y/x` for `tan(theta)`:

`y/x = tan(30^@)`

Multiply both sides by x:

`y = (tan(30^@))x`
