What is a cusp? Give examples.
Step 1 of 3</p>
In this problem, we have to define cusp with example.
Step 2 of 3</p>
A point at which two branches, such that the tangent of each branch are equal of a curve meet is
Consider a curve .
Differentiating both sides with respect to , we get
Hence, it is clear that the graph of this function becomes vertical and is a reflection of itself about the y-axis.
