[b]Good morning all, it is nice to be here again, how was the night? Let's quickly get down to the business of the day. DIFFERENTIATION OF PRODUCTS OF FUNCTIONS. Let y = uv, where u and v are functions of x. dy/dx = u[dv/dx] + v[du/dx]. To make things easier, let v' = dv/dx u' = du/dx. The new formular is given by: dy/dx = uv' + vu'. Short cut: To differentiate a product of two functions, put down the first (differentiate the second) + put down the second (differentiate the first). . . . . . . . . . . . . . . . . . . . . . . . . Example 1: find y' if y = x3 sinx Solution: y = x3 sinx since x3 and sinx are connected together by "multiplication-product", product rule is being use. y = x3 sinx let u = x3 u' = 3x2 let v = sinx v' = cosx. Therefore, dy/dx = uv' + vu' dy/dx = x3 cosx + sinx 3x2 dy/dx = x3 cosx + 3x2 sinx dy/dx = x2[x cosx + 3 sinx]. Short cut: y = x3 sinx y' = write the first which is x3, differentiate the second [cosx] + write the second which is sinx, differentiate the first [3x2] y' = x3 cosx + sinx 3x2 y' = x2[x cosx + 3 sinx] . . . . . . . . . . . . . . . . . . . . . . . . Example 2: y = x4 cosx, find y' Solution: y = x4 cosx. y' = x4 [-sinx] + cosx [4x3] y' = -x4 sinx + 4x3 cosx y' = 4x3 cosx - x4 sinx. . . . . . . . . . . . . . . . . . . . . . . . . Bonus: (a) y = sinx - cosx (b) y = 2x sinx + sinx cosx + 7. (c) y = (2x + 4)3 sin(3x + 6) Solution: (a) y = sinx - cosx, this question is polynomial, so we differentiate in turn y = sinx - cosx y' = cosx - (-sinx) y' = cosx + sinx. (b) y = 2x sinx + sinx cosx + 7. This question is combination of polynomial and product, therefore y = 2x sinx + sinx cosx + 7. y' = 2x (cosx) + sinx (2) + sinx (-sinx) + cosx (cosx) + 0. y' = 2x cosx + 2 sinx - sin2x + cos2x. (c) y = (2x + 4)3 sin(3x + 6). Very simple, lets go y' = [(2x + 4)3 (3) cos(3x + 6)] + [sin(3x + 6) [(3) (2x + 4)2 (2)]] y' = [3(2x + 4)3 cos(3x + 6)] + [6 (2x + 4)2 sin(3x+6)] . . . . . . . . . . . . . . . . . . . . . . . . Summary: 1. If y = uv, where u and v are functions of x. dy/dx = u[dv/dx] + v[du/dx]. 2. To differentiate a product of two functions, put down the first (differentiate the second) + put down the second (differentiate the first). . . . . . . . . . . . . . . . . . . . . . . . . Assignment: 1. No 39, 1997 d/dx cos (3x2 - 2x) is equal to. . . . 2. No 38, 1998 y = 243 (4x + 5)-2, find dy/dx when x = 1. 3. No 39, 1998 differentiate x wrt (x cosx) 4. No 34, 1999 What is the derivative of t2 sin(3t - 5) 5. No 40, 2000 if y = 2x cos2x - sin2x, find dy/dx when x = pi/4. (Hint pi = 22/7, but trig pi i.e sin(pi), cos(pi) e.t.c pi will assume 180¤ i.e sin(pi) = sin180¤, cos(pi) = cos180¤ e.t.c) 6. No 36, 2001 if y = x sinx, find dy/dx when x = pi/2 7. No 39, 2001 Differentiate (2x + 5)2(x - 4) wrt x 8. No 16, 2002 Find the derivative of y = sin2(5x). (Hint: sin2(5x) = sin(5x) sin(5x)) 9. No 36, 2003 if y = 3 sin(-4x), dy/dx is 10. No 35, 2004 find the derivative of (2 + 3x) (1 - x) wrt x 11. No 36, 2004 find the derivative of the function y = 2x2 (2x - 1) at the point x = -1 12. No 37, 2004 if y = 3 cos(x/3), find dy/dx when x = 3pi/2 (Hint: x/3 = 3-1x) 13. No 37, 2005 find the derivative of y = sin(2x3 + 3x - 4) 14. No 47, 2006 Differentiate (x2 - 1/x)2 wrt x 15.

I was playing with differentiation when a thought hit me concerning quotient rule. I will keep you in the loop during the next class. Things to note: 1. Note the difference between (cosx)-1 and cos-1x, the same for all trig. functions. 2. The quotient rule is dy/dx = [vu' - uv']/ v2. Congratulatory message: If you understood all the previous classes, welcome to the last aspect of basic differentiation (quotient rule). At this juncture (after quotient rule), I promise that differentiation will be a walk in the park. Till next class. |
