Differentiation of Trigonometric Functions from First Principles
Derivatives of Trigonometric Functions
- Notice how all "co" functions give a negative function upon differentiation.
- Likewise, all the "arc" functions give a fraction upon differentiation.
Tangent and Normal Formulae
- We've discussed how tangents and normals can be found using derivatives, but there is a more straightforward way to do so, using the following equations:
