The equation of the normal line is a mathematical formula that represents a line that is perpendicular to a given curve at a specific point. It can be written in the form y = mx + b, where m is the slope of the normal line and b is the y-intercept.
To find the equation of the normal line, we first need to find the slope of the tangent line at the given point on the curve. Then, we can use the fact that the slope of the normal line is the negative reciprocal of the tangent line's slope to determine the slope of the normal line. Finally, we can plug the slope and the coordinates of the given point into the equation y = mx + b to find the equation of the normal line.
Yes, the equation of the normal line can be used to find the slope of a curve at a specific point. This is because the slope of the normal line is the negative reciprocal of the slope of the tangent line at that point, which is equivalent to the slope of the curve at that point.
The equation of the normal line and the equation of the tangent line are similar in that they both represent lines that are tangent to a curve at a specific point. However, the normal line is perpendicular to the curve at that point, while the tangent line is parallel to the curve at that point. Additionally, the slopes of the normal and tangent lines are related by the fact that they are negative reciprocals of each other.
Yes, the equation of the normal line can be used to find the equation of the tangent line. This is because the slopes of the two lines are related by the fact that they are negative reciprocals of each other. Therefore, by finding the equation of the normal line, we can use the slope to find the equation of the tangent line.
