slava [35]

Answer:

$\huge\boxed{\dfrac{1}{5}=0.2}$

Step-by-step explanation:

$\dfrac{1}{2}-\dfrac{3}{10}=\dfrac{1\cdot5}{2\cdot5}-\dfrac{3}{10}=\dfrac{5}{10}-\dfrac{3}{10}=\dfrac{5-3}{10}=\dfrac{2}{10}=\dfrac{2:2}{10:2}=\dfrac{1}{5}\\\\\\\dfrac{1}{2}=0.5;\ \dfrac{3}{10}=0.3\\\\\dfrac{1}{2}-\dfrac{3}{10}=0.5-0.3=0.2$

Find the derivative:<br> f(x)=tan<img src="https://tex.z-dn.net/?f=%28x%5E%7B2%7D%20%2B5%29" id="TexFormula1" title="(x^{2} +5)"

Answer:

$2x \sec^2 (x^2 + 5)$

Step-by-step explanation:

$f(x) = \tan (x^2 + 5)$

$\dfrac{d}{dx} \tan u = \sec^2 u \dfrac{d}{dx} u$

$\dfrac{d}{dx} \tan (x^2 + 5) = \sec^2 (x^2 + 5) \dfrac{d}{dx} (x^2 + 5)$

$\dfrac{d}{dx} \tan (x^2 + 5) = [\sec^2 (x^2 + 5)]2x$

$\dfrac{d}{dx} \tan (x^2 + 5) = 2x \sec^2 (x^2 + 5)$
