- Prove that d/dx[cosx]=-sinxIntegrate trinometric functionsA 6-foot man walks on level ground toward a 50 foot flag pole. He notes different angles of elevation to the top of the pole when he is different horizontal distances x away from the pole. a) Express the man's horizontal distance from the base of the pole x (in feet) as a function of the angle of elevation in degrees. Type theta for 0. x= b) Express the angle of elevation as a function of the the man's horizontal distance to the base of the pole 0=
