Question

Prove algebraically that R(45+theta)=R(45-theta), that is, a given angle above 45 degrees will result in the same range as the same angle below 45 degrees. To prove it algebracially, you must not plug in any numbers other than 45 degrees. Start with the range formula, plug in (45+theta) for theta and simplify. Do the same for (45-theta).
