Find all solutions of each equation on the interval 0 ≤ x<2π.

Aleksandr [31]

Answer:

$x = 0 \: or \:x = \pi$

Step-by-step explanation:

The given equation is

$\tan^{2} (x) \sec^{2} (x) + \sec^{2} (x) - \tan^{2} (x) = 2$

Subtract 2 from both sides and factor by grouping to get:

$\sec^{2} (x)(\tan^{2} (x) + 2) -1( \tan^{2} (x) + 2)$

$(\tan^{2} (x) + 2) (\sec^{2} (x) - 1) = 0$

By the zero product principle:

$(\tan^{2} (x) + 2) = 0 \: or \: (\sec^{2} (x) - 1) = 0$

$(\tan^{2} (x) = - 2 \: or \: \sec^{2} (x) = 1$

When

$\sec^{2} (x) = 1 \implies\cos^{2} (x) = 1$

$\implies \: \cos(x) = \pm1$

This implies

$x = 0 \: or \:x = \pi$

When

${ \tan }^{2} (x) = - 2$

We have

$\tan(x) = \pm \sqrt{ - 2}$

hence x is not defined for all real numbers

Calculate the perimeter -math

Flauer [41]

That's easy

alrighty
we can see that each of those curves from K to N and from N to L are just 1/4 of the circumference of the circle
the circles have centers at J and M

so

we have 2 of those 1/4 circumfernce so a total of 2/4 or 1/2 circumference

circumference=2 times pi times radius
radius=JK=JN=NM=ML=7
we want half so
perimiter=1/2 times 2 times pi times 7
we are given pi=22/7 so
perimiter=1/2 times 2 times 22/7 times 7
perimiter=2/2 times 22
permiter=22cm

the perimiter is 22

wait, I forgot abou the bottom part (KL)
that's just twice the radius or 2*7=14
22+14=36
the perimiter is 36cm
