: Hey can anyone tell me how to find the derivative of the function
: y=(x-1)^4(x+2)^2
: using differential rules and not by expansion.
: Thank u....
: Derek
:Use y`= f`g+fg`
:f=(x-1)^4 f`=4(x-1)^3
:g=(x+2)^2 g`=2(x+2)
: y`=4(x-1)^3(x+2)^2 + 2(x-1)^4(x+2)
: The solution makes use of the product rule and the chain rule.
