1. ## limits
lim x→2g(x)
whereg(x) = ( x − 2 /x^ 2 − 4) if x 2
g(x)= 1 if x = 2
this confuses me any help would be nice ....
2. ## Re: limits
As it is written, your function is \displaystyle \begin{align*} x - \frac{2}{x^2} - 4 \end{align*}, but I suspect you meant \displaystyle \begin{align*} \frac{x - 2}{x^2 - 4} ... | HuggingFaceTB/finemath | |
What is the derivative of this function e ^ sin (2x)?
May 7, 2018
$\frac{d}{\mathrm{dx}} \left({e}^{\sin} \left(2 x\right)\right) = 2 {e}^{\sin} \left(2 x\right) \cos \left(2 x\right)$
Explanation:
Using the chain rule with $y = \sin t$ and $t = 2 x$ we have:
${e}^{\sin} \left(2 x\right) = {e}^{y}$
