The Special derivatives quiz exercise is exceptional and does not appear under a Math Mission in the The World of Math. In this exercise, students need to find the derivative of some special functions.

## Types of problems

There is one type of problem in this exercise.

1. Find the derivative: The problem shows a special function and the student is required to find its derivative.

## Strategies

1. Speed badges are attainable in this skill as there are only five possible problems in it: Find the derivative of ${\sin(x)}$, ${\cos(x)}$, ${\tan(x)}$, ${Ln(x)}$ and ${e^x}$. The derivatives of these functions are ${cosx}$, ${-\sin x}$, ${\sec^2(x)}$, ${\frac{1}{x}}$ and ${e^x}$ respectfully. They can be written precisely as they are written in the last sentence to achieve credit.
2. Their derivatives can be memorized and thus it is possible to answer a problem in less than five seconds.

## Real-life Applications

1. Calculus has massive applications to physics, chemistry, biology, economics and many other fields.
