The line tangent to a function at (assuming the derivative exists at this point) is found by the point slope formula:

Writing this in slope-intercept form, we have:

Now, using and can you now compute the required -intercept? - Nov 12th 2012, 12:19 AMcamjensonRe: Tangent Line
To be honest, no, I don't know where those variables would go in the equation...

First, compute the derivative of . Next, let and evaluate the

*y*intercept:

Isn't this the derivative -1/(x*[(ln(x))^(2)])?

So, in more simpler words, isn't it y-y1=m(x-x1)? y being the intercept y1 being the derivative after putting e/b in for x, m being the derivative, x being 0, and x1 being e/b? - Nov 12th 2012, 12:39 AMMarkFLRe: Tangent Line
Your derivative is correct, and next you correctly cite the point-slope formula for a line, but after that you contradict yourself/make wrong statements, and I am not sure what you really mean. I think what I stated is about as simple as it gets.
