Question

tell the derivative of log mod cosx​

Answer 1

Answer:

We know that the base of ln(x) is e, so we plug e in for a in the derivative formula to get that the derivativeformula of ln(x) is 1 / x(ln(e)). Now, recall that we said the logarithm loga (x) is equal to the number we raise a to get x. Therefore, ln(e) is equal to the number we raise e to in order to get e.

Step-by-step explanation:

To apply the chain rule, we first find the derivative of the outer function, lnu , with u=cosx . Remember that the derivative of lnu=1u=1cosx . Now we just need to find the derivative of the inner function, cosx , and multiply it by the derivative of the outer function we just found.
