I was trying to solve this integral x/(x-6)dx and I used substitution. u = x-6 and x = u+6. In the end, I ended up with the answer x+6ln|x-6|-6+C, however, the answer is x+6ln|x-6|+C without the -6. C...

I am trying to derive exponential function using logarithms. I know from below equation log(22026.4657948067), is 10 and exp(10) is 22026.4657948067 I would like to understand the basic math behind ex...

Firstly, I'm using this approximation of a natural log. Or look here (4.1.27) for a better representation of formula. Here's my implementation: constexpr double eps = 1e-12; constexpr double my_exp(c...

Is there a way to compute a natural log using decimal values in C#? I need something like decimal dec = Math.Log(decimalInput);` The problem is that Math.Log(x) only works with a double type as input...
