I have 2 equations on my homework that I am not allowed to use a calculator on, and need to find the exact answer/
Why would you try to use a calculator for these? Instead, try using the identities you've learned in trig and the factoring and solving techniques you learned back in algebra:I have 2 equations on my homework that I am not allowed to use a calculator on....
Apply a Pythagorean identity to convert the sine term to a cosine expression, solve the resulting quadratic-form equation for "cos(x)=", and then solve the two trig equations.
Convert the sine term using the double-angle formula, move one of the terms across the "equals" sign to join the other term, and factor the result. Then solve the two trig equations.
