The problem with this equation lies with the denominator on the left hand side. If we recall our graph of ln(x) however, we know that ln(x) is always positive and not equal to 0. Now we can safely multiply i...

This question requires for there to be a weighted answer, for and against the idea that the AMS system has more advantages. You need to give three answers for and three answers against. Each answer should ha...

Z is simply a general complex number, which can be written as Z = x+iyHere |Z-2+3i| = 1 can be written as |Z-(2-3i)| = 1, which is just an expression for every Z whose distance from the point (2,-3i) is equa...

The question says to use integration by parts on this question, but at the minute we only have one variable. Therefore, we introduce a 1, so that log|x|= 1*log|x|, here we have not altered the value of the f...

We can start by letting y = ln(x) What we are trying to show is that dy/dx = 1/x Since y = ln(x), then e y = e ln(x) = x Taking the derivative of each side of this equation will give us e y .dy/dx = 1 If we ...
