Find y' if x = tan(y)

Travka [436]

Use the chain rule:

$x=\tan y$
$\dfrac{\mathrm d}{\mathrm dx}x=\dfrac{\mathrm d}{\mathrm dx}\tan y$
$1=\sec^2y\dfrac{\mathrm dy}{\mathrm dx}$
$1=\sec^2y\,y'$
$y'=\dfrac1{\sec^2y}=\cos^2y$

Furthermore, if you restrict the domain of $y$ , we could write

$x=\tan y\iff \tan^{-1}x=y$

and so we could also have

$y'=\cos^2(\tan^{-1}x)=\left(\dfrac1{\sqrt{x^2+1}}\right)^2=\dfrac1{x^2+1}$

For any distribution, what is the z-score corresponding to the median? 0 1 n cannot be determined from the information given

defon

<span>This is a value that cannot be determined at current (choice D). The z-score associated with the mean is 0, but the median value is not always equal to the mean. In this case, it could be 0, it could be greater than 0, or it could be less than 0.</span>

4x−2y=14 y=12x−1 solve by substitution

Tatiana [17]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

I really need help on this, I don't quite understand what I am doing :.)

enot [183]

Subtract the two equations

f(x) - g(x)

(9x3 + 2x2 - 5x + 4) - (5x3 - 7x + 4)

9x3 + 2x2 - 5x + 4 - 5x3 + 7x - 4

4x3 + 2x2 + 2x
