Tugas Turunan1. y = 2x2 + 4x + 1y= 4x + 4

2. y = (2x2 + 4x + 1)60y= 60(2x2 + 4x + 1)59 . (4x + 4) = (240x + 240) . (2x2 + 4x + 1)59

3. y = y= =

4. y = cos3 (x2 +1)y= 3cos2 (x2 +1) . ( sin (x2 +1)) . (2x + 0) = 6x cos2 (x2 +1) . sin (x2 +1)

5. y = sin 3x + cos 2x + sec3 y= 3 cos 3x + ( 2sin 2x) + 3 sec2 . sec . tan . ()y= 3 cos 3x 2 sin 2x + sec2 . sec . tan

6. y = u = cos x dan u= -sin xv = x dan v= 1y= =

7. y = x2 sin xu = x2 dan u= 2xv = sin x dan v= cos xy= x2 cos x + 2x sin x

8. y = ln 3x5y= =

u = 15x4 dan u = 60x3v = 3x5 dan v = 15x4y= = =

u = -45x8 dan u= -360x7v = 9x10 dan v= 90x9 y= = =

9. y = , y= ?y= xx

u = xx dan u = xxv = xx dan v = xx y= xx . xx + xx . xx = x2x + x2x = x2x ( + 1)
