Title: Rules of differentiation Discussion Post by: bio_man on Sep 4, 2018 (https://biology-forums.com/gallery/38/6_04_09_18_8_09_16.png)
These rules you have nothing to worry about. They're there to make differentiation easier to do, that's all. Examples: \(f\left(x\right)=x±x^2\) You differentiate twice: \(\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(x^2\right)\) If they're being subtracted (minus), it's: \(\frac{d}{dx}\left(x\right)-\frac{d}{dx}\left(x^2\right)\) \(f\left(x\right)=3x^2\) This becomes: \(3\left[\frac{d}{dx}\left(x^2\right)\right]\) \(f\left(x\right)=3x^2+5\) becomes: \(\frac{d}{dx}3x^2+\frac{d}{dx}5\) \(3\left[\frac{d}{dx}x^2\right]+0\) ... |
