Please Help! Find the exact value: csec 22pi/3

1 answer:

6 0

Is this csec as in cosecant? If so, that would be csc 22pi/3. Through trigonometric identities, csc is just the inverse of sin. So it is equivalent to 1/sin(22pi/3). Make sure that your calculator is in radian mode. Then input this:

1/sin(22pi/3) = -1.15

If you actually meant sec 22pi/3, then that is equivalent to 1/cos(22pi/3):

1/cos(22pi/3) = -2

Either of those two is the answer :)

Will mark brainliest for having the steps. prove tan(2x) = tan(x+x)

jonny [76]

So here is how we are going to prove that (2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = 2(tanx−cotx)
------------------
tan^2−cot^2x
= 2(tanx−cotx)
----------------------
(tanx−cotx)(tanx+cotx)
= 2
-------------------
(tanx+cotx)
= 2
-----------------
Sin2x+cos2x
---------------- sinxcosx
= 2
-------------
1
------------
sinxcosx
= 2sinxcosx
= sin2x
I hope that is the answer that you are looking for. Let me know if you need more help next time. Thanks for posting your question here in brainly!

What is the domain of the function showing in the graph below? part 1

Llana [10]

Answer:

domain is x ∈ (- ∞, + ∞ )

Step-by-step explanation:

The graph shows

as y → - ∞ , x → - ∞

as y → + ∞ x → + ∞

The domain is therefore real for all values of x
