Webf(2+h) means use f(x) with an input of (2+h) = sqrt(2+h+4) = sqrt(6+h) Now, use these to create: (f(2+h)-f(2))/h = [sqrt(6+h)-sqrt(6)]/h The answer is simplified in this form. The … Web8 nov. 2015 · $\begingroup$ There is a way... it just mirrors the proof that $\sin' = \cos$. You'll end up with something very close to the classical $\frac{\sin x}{x}$ in the proof that will require further limits that are very hard to show without first knowing the derivative of sine... in short, it's much easier to just look at a proof of $\sin'(x)$ using limits and use that the …

Web1. Yes. In mathematics it is more common to use a single letter (sometimes a Greek letter), but a function name can be anything. After all it's just a way to communicate to other … WebIt says the correct answer is f (a)=a^3 :) Hint: We are given that f ( x) = x 3. Note that the x is just a placeholder. So if we want to figure out what f ( stuff) evaluates to, we just replace every instance of x with stuff. Hence, we know that: I got f (a) = 3a^2+3ah+h^2 which isn't correct answer. dr clark wolfeboro nh
