WebFrom my understanding, you'd like help with how to differentiate x^x. This is how you do it: y=x^x Take the logs of both sides: ln(y) = ln(x^x) Rule of logarithms says you can move a power to multiply the log: ln(y) = xln(x) Now, differentiate using implicit differentiation for ln(y) and product rule for xln(x): 1/y dy/dx = 1*ln(x) + x(1/x) WebInitially there are 9 grams of the isotope present. a.

WebSep 7, 2024 · Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. More generally, a function is said to be differentiable on S if it is ...
