What is the equation of the line tangent to f(x) 2x38x at x-1? Free tangent line calculator - find the equation of the tangent line given a point or the intercept step-by-step.Slope, Distance and More. Ski Vacation? Nope, this is serious stuff its about finding the slope of a line, finding the equation of a line To find the equation of a line you need a point and a slope.The normal line is a line that is perpendicular to the tangent line and passes through the point of tangency. In order to determine its slope it is necessary to understand the basic differentiation rules of differential calculus in order to find the derivative function f (x) of the initialOnce the slope is known, finding the equation of the tangent line is a matter of using the point- slope formula: (y - y1) (m(x - x1)).

Geometric Interpretation of Derivative: Slope of the Tangent Line.To find the equation of this tangent line, we need a point (x0, y0 ) on the line and the slope m of the line. To find the equation of a tangent line to a curve, use the point slope form (y-y1)m(x-x1), m being the slope.How do you find a slope of a line given an equation? You have to massage the equation around until its in a standard form, with Y all alone on one side of the equation, and So the question of finding the tangent and normal lines at various points of the graph of a function is just a combination of the two processes: computing the derivative at the point in question, and invoking the point- slope form of the equation for a straight line.
