Derivative of ln proof
WebSolving for y y, we have y = lnx lnb y = ln x ln b. Differentiating and keeping in mind that lnb ln b is a constant, we see that. dy dx = 1 xlnb d y d x = 1 x ln b. The derivative from above now follows from the chain rule. If y = bx y = b x, then lny = xlnb ln y = x ln b. Using implicit differentiation, again keeping in mind that lnb ln b is ... WebProof. Now, by making the substitution. One definition of Euler's number is. so the expression simplifies to.
