Equation of the normal line at a point


By TheIntegralCALC

http://integralcalc.com/ Learn how to find the equation of the normal line at a given point. To find the equation of the normal line, you'll need to first calculate the derivative of the function, then plug the given point into the derivative to find the slope of the tangent line. Plug the slope and the given point into the point-slope formula for the equation of the line to find the equation of the tangent line. Then take the negative reciprocal of the slope of the tangent line to find the slope of the normal line, which is the line perpendicular to the tangent line. Finally, plug the new slope and the given point into the point-slope formula for the equation of the line to find the equation of the normal line

Perpendicular lines are lines that intersect each other at right angles. In this video, Sal Khan demonstrates how to know which lines are perpendicular when solving an algebraic equation. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. (03:28) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.'
