put these polar equations into cartesians form:

1) theta=135 degrees
2)rcostheta=-1

for #1 is it like: (-1,1)?
and for #2, X=-1, but i cant find y, any help is appreciated

The slope should be sin(theta)/cos(theta) and the intercept is the origin.

x=r*cos(theta)
If r=1 we have x=cos(theta)

To convert polar equations into Cartesian form, you can use the following trigonometric relationships:

1) For a polar equation of the form θ = α, where α is the angle in degrees:

To convert this equation to Cartesian form, you can use the following relationships:
x = r * cos(θ)
y = r * sin(θ)

For θ = 135 degrees:
Using the relationships above, we have:
x = r * cos(135)
y = r * sin(135)

To find the Cartesian coordinates, we need to determine the value of r. In this case, it is not specified, so we cannot determine the specific Cartesian coordinates. However, we can calculate the values of x and y using the given angle θ.

2) For a polar equation of the form r * cos(θ) = α:

To convert this equation to Cartesian form, you can isolate r:
r = α / cos(θ)
Then, substitute r into the polar coordinates equations:
x = (α / cos(θ)) * cos(θ)
y = (α / cos(θ)) * sin(θ)

For r * cos(θ) = -1:
Substituting the values into the Cartesian coordinates equations, we have:
x = (-1 / cos(θ)) * cos(θ)
y = (-1 / cos(θ)) * sin(θ)

However, without knowing the specific value of θ, we cannot determine the exact Cartesian coordinates. But we can calculate x for given θ.

Keep in mind that for both cases, the resulting Cartesian coordinates may depend on the specific values of θ or r, which are not provided in the given equations.
