Use basic identities to simplify sin³ x + x + cos²x sinx. Enclose arguments of functions in parentheses. For example, sin (2x). Remember that writing sin(x) to the fourth power as sin4 (x) is just a mathematical shorthand. You should write it as (sin (x))4, which is what Mobius expects. sin³ x + cos² x sinx= DON
