I need help solving these problems please

4. [-/1 Points] DETAILS Verify the identity by converting the left side into sines and cosines. (Simplify at each step.) cot2 (t) _ 1 - sin2(t) 3 csc(t) 3 sin(t) cot? (t) cos(t)/ 3 csc(t) 3/sin(t) cos2(t) = 1 - sin2(t) 3 sin(t)3. [-/1 Points] DETAILS Verify the identity algebraically. Use the table feature of a graphing utility to check your result numerically. (Simplify at each step.) 6 cos(0) cot(@) - 6 = 6 csc(0) 1 - sin(0) 6 cos(0 ) cot(@) _ _ 6 cos(0) cot(0) - 6 (e)uis - I 1 - sin(0) 6 cos(0) - 6 + 6 sin(0) sin(0) = sin(0) sin (0) 1 - sin(0) 6 (cos2(0) + sin2(@)) - 6 sin(@) = (1 - sin(@) ) 6 - 6 sin(0) = )(1 - sin(8)) 6 = 6 csc(0)
