    Convert rectangular equation to polar equation

    How do I convert the hyperbola equation x^2/100^2 - y^2/75^2 = 1 to the polar form r = ed/1+ecos<theta>? Am I correct that c = 125 and e = c/a = 1.25?

    Hello, skierr4f3!

    How do I convert the hyperbola equation, \frac{x^2}{100^2} - \frac{y^2}{75^2} \:= \:1
    . . to the polar form: . r \:= \:\frac{ed}{1 + e \cos\theta} ?
    It can't be done directly . . .

    The rectangular form has its center at the origin.

    The polar form has a focus at the pole (origin).



    Am I correct that: c = 125 and e \,=\, \tfrac{c}{a} \,=\,1.25 ?
    Right!
