Which steps can be used to verify that tan(w pi) = tan(w)? rewrite tan(w pi) as tan(w) tan(pi). then simplify the expression using tan(pi) = 1. rewrite tan(w pi) as tan(w) tan(pi). then simplify the expression using tan(pi) = 0. rewrite tan(w pi) using the tangent sum identity. then simplify the resulting expression using tan(pi) = 1. rewrite tan(w pi) using the tangent sum identity. then simplify the resulting expression using tan(pi) = 0.
