Lim x-> infinity of arctan(lnx)

Mathematics

Lim x-> infinity of arctan(lnx)= arctan (infinity), because lnx-----> infinity when x ----> infinity

but  arctan (infinity) = Pi/2, so Lim x-> infinity of arctan(lnx)= Pi/2

The sum of two numbers is 26. Four less than four times the smaller number is equal to the larger number x. Find the larger numb
Svet_ta [14]
Hey there!

This question just wants you to create an equation and solve. In this case, the larger number is equal to x. To find the smaller number, we would need to multiply x by 4 and subtract 4 from it. This means that the smaller number is equal to (4x – 4). You add the two numbers, x and (4x – 4), to get 26. Your final equation is:

x + (4x – 4) = 26

Now, just solve. 

x + 4x – 4 = 26
(5x – 4) + 4 = (26) + 4
(5x) ÷ 5 = (30) ÷ 5
x = 6

Finally, just plug in 6 for both numbers to get your answer. 

(6) + (4(6) – 4) = 26
6 + 20 = 26

Your two numbers are 6 and 20. 

Hope this helped you out! :-)

what are the x-coordinates for the maximum points in the function f(x) = 4 cos(2x- pi) from x = 0 to x= 2 pi?
julsineya [31]

Answer:

\frac{\pi }{2} and \frac{3\pi }{2}

Step-by-step explanation:

To find the max points we need to take the derivative of the function and then find the critical values.

First we take the derivative:

f(x) = 4cos(2x-\pi )\\f'(x)=-4sin(2x-\pi )(2)\\f'(x)=-8sin(2x-\pi )\\

Now we need to find when f'(x)=0 to find the critical values.

0=-8sin(2x-\pi )\\0=sin(2x-\pi )\\sin^{-1}0=2x-\pi \\0=2x-\pi \\\pi =2x\\\frac{\pi }{2} =x

The critical values will be

\frac{\pi }{2} n for any integer n

between 0 and 2 pi, the critical values will be

0, \frac{\pi }{2} ,\pi ,\frac{3\pi }{2},2\pi

We can determine if these are minimums or maximums by using the second derivative test.

So we need to take the second derivative;

f'(x)=-8sin(2x-\pi )\\f''(x) = -8cos(2x-\pi )(2)\\f''(x)=-16cos(2x-\pi)

We need to see if the second derivative is positive or negative to determine if it is a max or min.

f''(0) = 16\\f''(\frac{\pi}{2})=-16\\f''(\pi )=16\\f''(\frac{2\pi}{3}) = -16\\

Since the second derivative is negative at

\frac{\pi }{2} and \frac{3\pi }{2}

we know both of those are the x-values of maximums.
