find the equation of the tangent line to y=ln(x), x=7
need some help...dont know how to do
Find the point: (7,ln(7))
Find the first derivative: y' = 1/x
Evaluate the derivative at the given point. m = 1/7
Use the Point-Slope form of a line to write the equation. I'll leave the exercise for you.
Hint: There is a reason why I called the specific value of the derivative "m".
