Basic Derivative Information and Power Rule
Define the Quotient Rule using f(x) / g(x)
[g(x)f′(x) - f(x)g′(x)] / (g(x))²
Differentiate y= 2 / (x+1)
y′ = -2 / (x+1)²
Differentiate y= 32x / (x²-lnx)
y′= [(x²-lnx)(2ln3•32x)–32x(2x–1/x)] / (x²-lnx)²
Differentiate y=√(13x²–5x+8)
y′ =(26x–5) / 2√(13x²–5x+8)
Differentiate y=e-x² cos2x
y′ =−2xe-x² cos2x−2e-x² sin2x
f(x)= (x²-1)³ / x²+1, what is f′(x)?
f′(x)= [(x²+1)•6x(x²-1)2–2x(x²-1)³] / (x²+1)²
d/dx arcsec(x)=
1 / |x| √(x² - 1)
d/dx log(x)
1 / x ln(10)
Differentiate y=3tan√(x)
y′ =3sec²√(x) / 2√(x)
Differentiate y= x³lnx / x+2
y′ = [(x+2)(3x2lnx+x2)–x³lnx] / (x+2)²
d/dx arccot(2x)
-2 / 4x2+1
