Hello!
Explanation:
This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left to right.
Do parenthesis first.
![1+2=3](https://tex.z-dn.net/?f=1%2B2%3D3)
![(3-5)*2-8](https://tex.z-dn.net/?f=%283-5%29%2A2-8)
![-2*2-8](https://tex.z-dn.net/?f=-2%2A2-8)
Multiply left too right.
![-2*2=-4](https://tex.z-dn.net/?f=-2%2A2%3D-4)
![-4-8](https://tex.z-dn.net/?f=-4-8)
![=-12](https://tex.z-dn.net/?f=%3D-12)
Add/subtract left too right.
![1+2(-12)](https://tex.z-dn.net/?f=1%2B2%28-12%29)
Multiply left to right.
![2(-12)=-24](https://tex.z-dn.net/?f=2%28-12%29%3D-24)
![1-24=-23](https://tex.z-dn.net/?f=1-24%3D-23)
Answer: ![\boxed{=-23}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D-23%7D)

The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.
Answer:
Step-by-step explanation:
2/cos^2(theta) - sin^2(theta)/cos^(theta) = p
(2 - sin^2(theta) ) / cos^2(theta) = p
cos^2(theta) = 1 - sin^2(theta) Relationship between sines and cosines
2 - sin^2(theta)/ (1 - sin^2(theta) ) = p Everything is now in terms of sines
sin^2 (theta) = 1 / csc ^2 (theta) sin^(theta) = 1/csc(theta)
2 - 1/csc^2(theta) Make Left over csc(theta)
============== = p
1 - 1/csc^2(theta)
2 csc^2(theta) - 1
------------------------
csc^2(theta)
================ = p Cancel out denominators (csc^2(theta))
csc(theta) - 1
-------------------
csc^2(theta)
2 csc^2 (theta) - 1
=============== = p Multiply both sides by csc^2(theta) - 1
csc^2(theta) - 1
2csc^2(theta) - 1 = p*csc^2(theta) - p Collect csc^2(theta) on the left, p on the right.
csc^2(theta) (2 - p) = 1 - p
csc^2(theta) = (1 - p)/(2 - p)
