Find the equation of the tangent line to a polynomial curve at a given point. Computes the slope f'(a) and builds y - f(a) = f'(a)(x - a).
Find the equation of the tangent line to a polynomial curve at a given point. Computes the slope f'(a) and builds y - f(a) = f'(a)(x - a).
Enter comma-separated coefficients starting from the highest degree term.
The tangent line passes through (a, f(a)) with slope f'(a). Rearranging gives the line in slope-intercept form.
