WebSo we've already seen that the derivative with respect to x of e to the x is equal to e to x, which is a pretty amazing thing. One of the many things that makes e somewhat special. Though when you have an exponential with your base right over here as e, the derivative of it, the slope at any point, is equal to the value of that actual function. WebNov 11, 2024 · Answer: The Derivative of cos 4 x is − 4 cos 3 x sin x. Proof: Step 1: Let us assume that z = cos x. Then we can write our function as cos 4 x = z 4 Step 2: Note that d z d x = − sin x as z = cos x. Step 3: By the chain rule, the derivative of cos 4 x will be equal to d d x ( cos 4 x) = d d z ( z 4) ⋅ d z d x

How to find the derivative of x^4? Socratic
WebBasically, you need to start over, and find the derivative of f(x) = x^u, where u is some function of x, and you will find d/dx(x^u) = x^u(ln(x)(du/dx) + u/x). So you find out, shockingly, that the 1 in the derivative was not really a 1! It was (exponent/base) which only becomes 1 when the exponent and base are both x!
