Question Sequence

Question 1

Recall that a tangent line to a graph of y = f(x) at a point P(a, f(a)) is the line through the point P of slope . The equation of the tangent line in point-slope form is y - = ยท(x - a).

Incorrect
Correct

 
Step 2

We must now find the slope of the tangent line at the point of tangency, (1,ln(2)), by calculating the derivative of s(t) and evaluating the derivative at t = 1.
