what is the formula for slope of a tangent line. Find the equation of the tangent to the parabola x 2 x 2y 2 0 at 1 2 Solution. Solution for What is the equation of the curve whose tangent line passes through the point 12 with slope given by the value of the integral.
Y1 3x1 y - - 1 3 x - - 1. We will find the slope of the tangent line by using the definition of the derivative. Plug in the slope of the tangent line and the x x and y y values of the point into the point - slope formula yy1 mxx1 y - y 1 m x - x 1.
Y - y1 m x - x1.
F 2 22. Slope of tangent at 1 2. Your job is to find m which represents the slope of the tangent line. The equation for the slope of the tangent line to fx x2is f x the derivative of fx.
