constant rule

derivative of a constant is zero.

constant multiple rule

derivative of a constant multiplied by a fxn is the constant times the derivative of the fxn.

power rule

the derivative of x^n is n*x^(n-1), where n is a real number.

sum and difference rule

the derivative of a sum or difference of fxns is the sum or difference of their derivatives.

product rule

the derivative of a product of two fxns is the first fxn times the derivative of the second plus the second fxn times the derivative of the first.

quotient rule

derivative of a quotient of two fxns is the denom x the derivative of the num - the num x the derivative of the denom, / denom²
