For example, if y = xx , then log y = x log x1/y. dy/dx = log x + 1dy/dx = y. (logx + 1)= xx (logx + 1)Higher-Order DifferentiationWe find higher-order derivatives on successive differentiation. The further differentiation of the first derivative is denoted by f'' or d2...
Hence, we have determined the value of log e using the change of base formula. Another way to find the value of log e is using the value of e. We know that the value of e is approximately 2.71828. So, on substituting this value into the expression log x, we have log e = log10...
