Find the derivative of the function using the power rule or another differentiation method. 2. Plug in the x-coordinate into the derivative to find the slope of the tangent line at that point. 3. Use the point-slope formula, y - y1 = m (x - x1), where m is the slope and (x1, y1) is the given point, to find the equation of the tangent line. 5.The tangent vector given by the derivative of a parametrized curve forms the basis for the equation of a line tangent to the curve.The tangent line to a curve at a given point is a straight line that just "touches" the curve at that point. So if the function is f (x) and if the tangent "touches" its curve at x=c, then the tangent will pass through the point (c,f (c)). The slope of this tangent line is f' (c) ( the derivative of the function f (x) at x=c).
