Study Notes
Continuity and Discontinuity
- A cusp is a type of discontinuity in a function.
- A cusp is a point where a function is not continuous.
- Despite this, the derivative of a function is still defined at a cusp.
Singularities
- A cusp is a type of singularity where the function is not defined.
Function Continuity
- The existence of a cusp in a function does not affect the overall continuity of the function.
