To get more practice in calculus, we brought you this problem of the week:

How would you differentiate \({e}^{x}-\tan{x}\)?

Check out the solution below!



\[\frac{d}{dx} {e}^{x}-\tan{x}\]

1
Use Sum Rule: \(\frac{d}{dx} f(x)+g(x)=(\frac{d}{dx} f(x))+(\frac{d}{dx} g(x))\).
\[(\frac{d}{dx} {e}^{x})-(\frac{d}{dx} \tan{x})\]

2
The derivative of \({e}^{x}\) is \({e}^{x}\).
\[{e}^{x}-(\frac{d}{dx} \tan{x})\]

3
Use Trigonometric Differentiation: the derivative of \(\tan{x}\) is \(\sec^{2}x\).
\[{e}^{x}-\sec^{2}x\]
