Answer:

- $\frac{1}{2}$

Step-by-step explanation:

Given

$\frac{x^2y^8}{x^7y^6}$

= $\frac{y^{(8-6)} }{x^{(7-2)} }$

= $\frac{y^2}{x^5}$ , substitute values

= $\frac{4^2}{(-2)^{5} }$

= $\frac{16}{-32}$

= - $\frac{1}{2}$

Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer

lyudmila [28]

$f(\theta)=10\cos\theta+5\sin^2\theta$

then the derivative is

$f'(\theta)=-10\sin\theta+10\sin\theta\cos\theta$

Critical points occur where $f'(\theta)=0$ . This happens for

$-10\sin\theta+10\sin\theta\cos\theta=0$

$-10\sin\theta(1-\cos\theta)=0$

$\implies-10\sin\theta=0\text{ or }1-\cos\theta=0$

In the first case, we find

$-10\sin\theta=0\implies\sin\theta=0\implies\theta=n\pi$

In the second,

$1-\cos\theta=0\implies\cos\theta=1\implies\theta=2n\pi$

So all the critical points occur at multiples of $\pi$ , or $n\pi$ . (This includes all the even multiples of $\pi$ .)
