Differentiation rules describe simple rules that can be used to compute a derivative of a function without using the formal limit as shown below.
| Function | Derivative | Example |
|---|---|---|
| $$\sin{x}$$ | $$\cos{x}$$ | $$\deriv{}{x}\sin{x^2}=\cos{x^2} \cdot 2x$$ |
| $$\cos{x}$$ | $$-\sin{x}$$ | $$\deriv{}{x}\cos{x^2}=-\sin{x^2} \cdot 2x$$ |
| $$\tan{x}$$ | $$\sec^2{x}$$ | $$\deriv{}{x}\tan{x^2}=\sec^2{x^2} \cdot 2x$$ |
| Function | Derivative | Example |
|---|---|---|
| $$\csc{}x$$ | $$-\csc{}x\cot{}x$$ | $$\deriv{}{x}\csc{x^2} = -\csc{x^2}\cot{x^2} \cdot 2x$$ |
| $$\sec{x}$$ | $$\sec{x}\tan{x}$$ | $$\deriv{}{x}\sec{x^2} = \sec{x^2}\tan{x^2} \cdot 2x$$ |
| $$\cot{x}$$ | $$-\csc^2{x}$$ | $$\deriv{}{x}\cot{x^2} = -\csc^2{x^2} \cdot 2x$$ |
| Function | Derivative | Example |
|---|---|---|
| $$\sin^{-1}{x}$$ | $$\frac{1}{\sqrt{1-x^2}}$$ | $$\deriv{}{x}\sin^{-1}{x^2} = \frac{1}{\sqrt{1-x^4}} \cdot 2x$$ |
| $$\cos^{-1}{x}$$ | $$\frac{-1}{\sqrt{1-x^2}}$$ | $$\deriv{}{x}\cos^{-1}{x^2} = \frac{-1}{\sqrt{1-x^4}} \cdot 2x$$ |
| $$\tan^{-1}{x}$$ | $$\frac{1}{1+x^2}$$ | $$\deriv{}{x}\tan^{-1}{x^2} = \frac{1}{1+x^4} \cdot 2x$$ |
| $$\csc^{-1}{x}$$ | $$\frac{-1}{\mid x\mid\sqrt{x^2-1}}$$ | $$\deriv{}{x}\csc^{-1}{x^2} = \frac{-1}{\mid x^2 \mid\sqrt{x^4-1}} \cdot 2x$$ |
| $$\csc^{-1}{x}$$ | $$\frac{-1}{\mid x \mid \sqrt{x^2-1}}$$ | $$\deriv{}{x}\csc^{-1}{x^2} = \frac{-1}{\mid x^2 \mid \sqrt{x^4-1}} \cdot 2x$$ |
| $$\cot^{-1}{x}$$ | $$-\frac{-1}{1+x^2}$$ | $$\deriv{}{x}\cot^{-1}{x^2} = \frac{-1}{1+x^4} \cdot 2x$$ |
| Function | Derivative | Example |
|---|---|---|
| $$\ln{x}$$ | $$\frac{1}{x}$$ | $$\deriv{}{x}\ln{x^2}=\frac{1}{x^2} \cdot 2x$$ |
| $$\ln(-x)$$ | $$\frac{1}{x}$$ | $$\deriv{}{x}\ln(-x^2)=\frac{1}{x^2} \cdot 2x$$ |
| $$\log_{a}{x}$$ | $$\frac{1}{x\ln{a}}$$ | $$\deriv{}{x}\log_{a}{x^2}=\frac{1}{x^2\ln{a}} \cdot 2x$$ |
| $$e^{x}$$ | $$e^{x}$$ | $$\deriv{}{x}e^{x^2}=e^{x^2} \cdot 2x$$ |
| $$a^{x}$$ | $$a^{x}\ln{a}$$ | $$\deriv{}{x}4^{x^2}=4^{x^2}\ln{4} \cdot 2x$$ |
