So first off, the tangent line is just going to be a straight line:
so, in order to find this equation we can use the point slope formula:
Now that we have that in mind, we have a point (0, 0). Now all we need is the slope (i.e., the derivative at that point).
I get (without simplification):
Why not simplify? because I can just plug in (0, 0) and most of that mess will just disappear.
Plug your slope back into the point slope formula and voila!
Hope that helps!
