Simple differentiation | 1. | 2. 5 cos (2 - x2) = -5 sin (2 - x2)(-2x) = 10xsin (2 - x2) |
3. | 4. -12x2cos (3 - 4x3) | |
5. y' = -15 sin 5x - 15 cos 5x | 6. y' = 2π sec2πx - 3e sin ex | |
Chain rule | 7. y = tan2 x
|
8. y = 3(1 + 2sin x)3
|
9. y = cos(sin 3x)
y' = -sin (sin 3x)× (cos3x) × 3 = -3 cos 3x (sin (sin 3x)) |
