Homework Statement
Find the value of the following derivative at x=1:
d/dx(2v/u)
where u(1)=3, u'(1)=-4, v(1)=-2, v'(1)=5
The Attempt at a Solution
Differentiating the equation:
[(u)(2v') - (u')(2v)]/(u^2)
plugging in the values i get 14/9 as the value.
now my question arises from the derivative of 2v. Would it be just 2? or 2v' as v represents a 'complex base' (therefore using the chain rule)??
the question seems simple enough to me as well but i just want to clarify this.
thanks.
