How do you differentiate y=cos^2x
|
Chain rule
y=u^2 dy/du=2U u= cosx du/dx = -sinx dy/dx= -2sinxcosx |
|
|
How do you differentiate y=cos2x
|
Chain Rule
y=cosu dy/dx= -sinu u=2x du/dx=2 dy/dx= -2sin2x |
|
|
cos2x can also be writted as
|
cos^2 x - sin^2 x
2cos^2 x -1 1-2sin^2 x |
|
|
With the Binomial Expansion (p+qx)^n, if n is a negative integer or fraction, it is only valid when
|
I QX/P I < 1
