For the following exercises, algebraically determine whether each of the given expressions is a true identity. If it is not an identity, replace the right-hand side with an expression equivalent to the left side. Verify the results by graphing both expressions on a calculator. sin(2x)+sin(4x) sin(2x) sin(4x) -tan(3x)cot x
