How do you differentiate #f(x)= (2 x^2 + 7 x - 2)/ (x cos x )# using the quotient rule?
This will also require a use of the product rule for the function in the denominator.
The quotient rule states that for some function
Using that idea we are going to need to find
Substituting into the rule, the derivative is equal to:
You can then simplify as required.
The given equation is
We use the formula for derivative of rational expression
We simplify at this point
God bless....I hope the explanation is useful.
