I have plotted both my answer and Pressley's answer, and it seems like Pressley's answer doesn't even make sense. The curve is depicted in blue, the tangent line is depicted in green, the normal line is depicted in orange, and the valueγ(π/4)=(2–√,2–√−1)γ(π/4)=(2...

The normal line is a line that is perpendicular to the tangent line and passes through the point of tangency. Examples Example 1 Suppose $$f(x) = x^3$$. Find the equation of the tangent line at the point where $$x = 2$$. Step 1 Find the point of tangency. Since $$x=2$$...
A normal is a line that intersects a curve at two points. The angle between the normal and the curve is always 90 degrees. Normals can be used to find the equation of a curve at a certain point.Tangents and normals are two important concepts in geometry. Tangents are used to find ...

We often need to find tangents and normals to curves when we are analysing forces acting on a moving body.A tangent to a curve is a line that touches the curve at one point and has the same slope as the curve at that point.
