Basic Derivative Information and Power Rule
The derivative calculates the ________.
Slope of the tangent line
Define the Product Rule using f(x)g(x)
f′(x)g(x)+ g′(x)f(x)
or
f(x)g'(x)+g(x)f'(x)
d/dx 1/√(x)
-1/2 x-3/2
Differentiate y=x³cosx
y′ =x3(-sinx)+cosx(3x2)
Differentiate y= (1+cotx) / (x²-2x)
y′= [(x²-2x)(-csc2x)-(1+cotx)(2x-2)]/(x²-2x)2
d/dx 1/x - 1/x3 =
-x-2 + 3x-4
Differentiate y=(2x-5)-2(x2-4x)6
y′ =2(x2-4x)5(2x-5)-3(10x2-46x+60)
Differentiate y=x5cos2x
y′ =x5(-sin2x)(2) + cos2x (5x4)
The rate of change of position is
velocity
Differentiate y= (x³sinx)/(x+2)
y′ = (x3cosx)(x+2)+(2x2sinx)(x+3)/(x+2)2
d/dx secx=
y'=secxtanx
