WebMar 30, 2024 · Ex 13.2, 10 Find the derivative of cos x from first principle. Let f (x) = cos x We need to find f’(x) We know that f’(x) = (𝑙𝑖𝑚)┬(ℎ→0) 𝑓⁡〖(𝑥 + ℎ) − 𝑓(𝑥)〗/ℎ Here, f (x) = cos x So, f (x + h) = cos (x + h) Putting values, f’ … WebLynn. 5 years ago. The derivative of e^u = e^u*du/dx. Therefore, if u=x, the derivative would equal e^x*1, which is the same as e^x. An example of something more complex, such as the derivative of e^x^2 would be: u=x^2, so the answer would be 2e^x^2. 2 comments.

WebWith respect to the quantity that is actually changing in the limit, namely delta x, cos(x) is a constant and so can be taken outside of the limit. If this is not clear, delta x could be called something else, say h, to make it more clear that cos(x) is considered a constant in this limit and so can be taken outside of the limit.
