d/dx f(g(x))

To find the derivative of the composite function f(g(x)) with respect to x, we can use the chain rule. The chain rule states that if y = f(u) and u = g(x), then the derivative of y with respect to x is given by:
dy/dx = dy/du * du/dx.
In this case, let’s assume that f(u) is differentiable and g(x) is also differentiable.
So, we have:
y = f(g(x)).
Now, let’s find the derivative dy/dx:
dy/dx = df(g(x))/dx.
To simplify this, we’ll apply the chain rule:
dy/dx = df(g(x))/dg(x) * dg(x)/dx.
This gives us:
dy/dx = f'(g(x)) * g'(x).
So, the derivative of f(g(x)) with respect to x is:
d/dx f(g(x)) = f'(g(x)) * g'(x).
Note that f'(g(x)) represents the derivative of f with respect to g(x), while g'(x) represents the derivative of g with respect to x.
