Web3. Rate of Change. To work out how fast (called the rate of change) we divide by Δx:. ΔyΔx = f(x + Δx) − f(x)Δx. 4. Reduce Δx close to 0. We can't let Δx become 0 (because that would be dividing by 0), but we can make it head towards zero and call it "dx":. Δx dx. You can also think of "dx" as being infinitesimal, or infinitely small.. Likewise Δy becomes very small … WebLet f be the function defined for x > 0, with fe()= 2 and f ′, the first derivative of f, given by f ′()xx x= 2 ln . (a) Write an equation for the line tangent to the graph of f at the point ()e,2 . (b) Is the graph of f concave up or concave down on the interval 1 3 ?<

In f (x) = ln (cos (x)), we have a function of a function (it's not multiplication, just sayin'), so we need to use the chain rule for derivatives: For this problem, with f (x) = ln (x) and g (x) = cos (x), we have f ' (x) = 1/x and g' (x) = - sin (x), then we plug g (x) into the formula for f ' ( * ). = −sin(x) cos(x) = − tan(x).
