Homework Help: Solving for variables

  1. Nov 23, 2004 #1
    i have an equation ((r^2)*(-i/(w*c)))+(r/(w*c))
    divided by (r^2) + (1/(wc)^2)
    equals -951 - (i*13026)

    where i is the square root of negative one and w is known. How do I get two equations to solve for both c and r.

    Assuming "r" and "c" to be real numbers, equate the real parts in your equation, and the imaginary parts in your equation:
    [tex]\frac{\frac{r}{wc}}{r^{2}+\frac{1}{(wc)^{2}}}=-951[/tex]
    And:
    [tex]-\frac{\frac{r^{2}}{wc}}{r^{2}+\frac{1}{(wc)^{2}}}=-13026[/tex]
