Answer the following. Write your answer on a separate sheet of paper. 1. Differentiate y = x2 sin x 2. What is the derivative of y = 3 sin x - 4 cos x? 3. By applying the product rule, differentiate y = x3 tanx. 4. Solve the derivative of y = csc x cot x by applying the product rule. 5. y =. (sin x) 2 ( cos x ) 2 ' what is y'? Solve for the derivative of the following functions. Write your answer on a separate sheet of paper. 6. y = x sin(2x) 11. y = csc(2x2) 7. y = cos(x2) 12. y = csc(3x2 + 1) 8. y = cos2x 13. y = 2 sec x + 50 9. y = tan(sinx) 14. y = -3 sec(6x) 10.y = tan(4x - 1) 15. y = 3 cot(5x)
