So you don't know the derivative of
(I assume the function is
Let's write the definition:
You know
So, by Leibniz
So the equation of the tangent line is
Which means
graph{1/2xln(x^2) [-10, 10, -5, 5]}
graph{y=x+1 [-10, 10, -5, 5]}
For
to find the slope of the tangent line at
Usually, I like to use the fact that
To find
So,
And at the point of interest:
I assume you can find the equation of the line through
