Calculus/Quotient Rule

Product Rule Derivatives of Trigonometric Functions Quotient rule There rule similar to the product rule for quotients. To prove it, we go to the definition of the derivative: This leads us to the so-called "quotient rule": Derivatives of quotients (Quotient Rule) Which some people remember with the mnemonic "low D-high minus high D-low (over) square the low and away we go!" Examples The derivative of is: Remember: the derivative of a product/quotient is not the product/quotient of the derivatives. (That is, differentiation does not distribute over multiplication or division.) However one can distribute before taking the derivative. That is
