Calculus I (math 170) Derivative Identities
Term | Definition |
---|---|
f'(a) as a approaches 0 (using h) | f(a+h)-f(a)/h |
f'(a) as a approaches 0 (no h) | f(x)-f(a)/x-a |
Slope intercept form | y=f'(a)(x-a)+f(a) |
(x^n)' | nx^n-1 |
(f+g)' | f'+g' |
c=constant (cf)' | c(f)' |
(fg)'(x) | f(x)g'(x)+g(x)f'(x) |
(f/g)'(x) | g(x)f'(x)-f(x)g'(x)/g(x)^2 |
(f(g(x)))' | f'(g(x))g'(x) |
(f(x)^n)' | n(g(x))^n-1 g'(x) |
(e^g(x))' | g'(x) e^g(x) |
(f(mx+b))' | m f'(mx+b) |
b^x (using ln) | (lnb)b^x |
(lnx)' | 1/x |
ln(f(x)) | f'(x)/f(x) |
