How to take derivatives of logs
WebWhen we take the logarithm of a number, the answer is the exponent required to raise the base of the logarithm (often 10 or e) to the original number. For example log base 10 of 100 is 2, because 10 to the second power is 100. ... Derivatives of Logarithms and Exponentials. The derivatives of the natural logarithm and natural exponential ...

WebThe natural log of x is only defined for positive values of x, but when you take the absolute value, now it could be negative or positive values of x. And it works, the derivative of this is indeed one over x. Now it's not so relevant here, because our bounds of … WebMay 23, 2015 · What you can do is let f ( x, y) = log y ( 9 x). Then using change of base, f ( x, y) = ln ( 9 x) ln ( y). Then f y = ln ( y) 0 − ln ( 9 x) 1 y ln 2 ( y) = − ln ( 9 x) y ln 2 ( y) Edit: I interpreted the post to mean log base y, others might have interpreted differently. Why did you derivate ln ( 9 x) ,shouldn't it be constant? I used ...
