Thread: Equation of the Tangent Line

For the function f(x) = x^2 + 2 * (tan x) - 2
Find the equation of the tangent line to the graph of f(x) at the point (0,-2).

If you have 6 mcflurries, and you buy another one, how many mcflurries do you have?

Find f'(x). Then plug in 0 into the derivative to find f'(0), the slope of the tangent line at that point. Call this m. Then plug in your point (0, -2) and your slope (m) in to the equation of the line

(where (x1, y1) represents your point).
