Find the length of the curve. R(t) = cos(8t) i + sin(8t) j + 8 ln cos t k, 0 ≤ t ≤ π/4

arsen [322]

we are given

$R(t)=cos(8t)i+sin(8t)j+8ln(cos(t))k$

now, we can find x , y and z components

$x=cos(8t),y=sin(8t),z=8ln(cos(t))$

Arc length calculation:

we can use formula

$L=\int\limits^a_b {\sqrt{(x')^2+(y')^2+(z')^2} } \, dt$

$x'=-8sin(8t),y=8cos(8t),z=-8tan(t)$

now, we can plug these values

$L=\int _0^{\frac{\pi }{4}}\sqrt{(-8sin(8t))^2+(8cos(8t))^2+(-8tan(t))^2} dt$

now, we can simplify it

$L=\int _0^{\frac{\pi }{4}}\sqrt{64+64tan^2(t)} dt$

$L=\int _0^{\frac{\pi }{4}}8\sqrt{1+tan^2(t)} dt$

$L=\int _0^{\frac{\pi }{4}}8\sqrt{sec^2(t)} dt$

$L=\int _0^{\frac{\pi }{4}}8sec(t) dt$

now, we can solve integral

$\int \:8\sec \left(t\right)dt$

$=8\ln \left|\tan \left(t\right)+\sec \left(t\right)\right|$

now, we can plug bounds

and we get

$=8\ln \left(\sqrt{2}+1\right)-0$

so,

$L=8\ln \left(1+\sqrt{2}\right)$ ..............Answer

Combine like terms to find the equivalent expression to6(58u+1)−6(−74u−5).

gtnhenbr [62]

Answer:

-36 • (22u + 1)

Step-by-step explanation:

Pulling out like terms :

2.1 Pull out like factors :

-74u - 5 = -1 • (74u + 5)

Equation at the end of step 2 :

(6 • (58u + 1)) - -6 • (74u + 5)

Step 3 :

Equation at the end of step 3 :

6 • (58u + 1) - -6 • (74u + 5)

Step 4 :

Pulling out like terms :

4.1 Pull out 6

Note that -6 =(-1)• 6

After pulling out, we are left with :

6 • ( (-1) * (58u+1) +( (-1) * (74u+5) ))

Step 5 :

Pulling out like terms :

5.1 Pull out like factors :

-132u - 6 = -6 • (22u + 1)

Final result :

-36 • (22u + 1)

N+12=4 what is the process of the equation

Sunny_sXe [5.5K]

Hey there!

Here is your question -

$n+12=4$

In this equation, you're looking for n alone. To keep the variable alone, you have to do the opposite of what's happening to the variable.

In this equation, 12 is being added to n. The opposite of that is subtracting 12.

Subtract 12 from both sides -

$n+12-12=4-12 \\ n=-8$

Your answer is -8.

Hope this helps! :)
