How do i solve for the area of a circle?
Example:
symbol r("r");
ex e = pow(r,2) * Pi == 30;
ex solve = lsolve(e,r);
//This example does not work. An error message
indicating that this is not a linear equation is
returned. How do I solve for "r" in this case.
//Could you also show an example of how to solve for a
simple polynomial, such as:
ex = pow(a,2) + a = 3
How do i solve for "a".
regards,
Tom Brikman
