You should know the definition of the derivative

Know The Power Rule: ( xn )’ = n xn-1

( sin(x) )’ = cos(x)

( cos(x) )’ = -sin(x)

( tan(x) )’ = sec2(x)

( cot(x) )’ = -csc2(x)

( sec(x) )’ = sec(x) tan(x)

( csc(x) )’ = -csc(x) cot(x)

 

( arcsin(x) )’ = 1/sqrt(1-x2)

( arccos(x) )’ = -1/sqrt(1-x2)

( arctan(x) )’ = 1/(1+x2)

( arccot(x) )’ = -1/(1+x2)

( arcsec(x) )’ = 1/sqrt(x2-1)

( arccsc(x) )’ = -1/sqrt(x2-1)

 

( sinh(x) )’ = cosh(x)

( cosh(x) )’ = sinh(x)

 

( ex ) ‘ = ex

( ln(x) )’ = 1/x

 

The Product Rule: (f*g)’ = f’*g + f*g’

The Quotient Rule: ( f / g )’ = (g*f’ – f*g’) / g2

The Chain Rule: ( f(g(x)) ) ‘ = f'(g(x)) * g'(x)

Implicit Differentiation


Some good elementary practice exercises from Thomas’ Calculus:Early Transcendental Functions, 11th ed.

Section 3.1 #27-43

Section 3.2 #1-46

Section 3.3 #1-30

Section 3.4 #1-46

Section 3.5 #1-108

Section 3.6 #1-66

Section 3.7 #1-96

Section 3.8 #49-74

Section 3.10 #1-66

Other exercises in these sections are good for providing deeper insight into the derivative.
