Normal Line Normal Line Calculator Practice Lesson Summary Frequently Asked Questions How do you find the equation of a tangent line and a normal line? To find the equation of tangent and normal lines to a curve y = f(x) at a point (c, f(c)), we first need f'(c), which is ...
A tangent line to a curve is the straight line that just touches the curve at a given point. At such a point, the slope of the curve must be equal to the slope of the tangent line. The tangent line is often used to locate optimal choices in constrained optim...
The vector (Rx, Ry) is normal to the level curve defined by R = 0, so the vector (Ry,–Rx) is tangent to the level curve. The differential equations just specify to traverse the curve by following the tangent vector. The main problem with the former algorithm is that numerically findin...
