Answer: y2/4 - x2/5
Step-by-step explanation:
Answer:
A_ 1,2,4,5,-1, or,-2
3 plus any of these will always leave you with a positive number of 1-8
B_ -1, -3, -4, -5, or 1
-2 plus any of these will leave you with a negative number of -7 through -1
C_ 1+(-1)
2+(-2)
3+(-3)
4+(-4)
5+(-5)
since all the numbers are 1-5 are both negative and positive these will cancel out and equal to zero.
Step-by-step explanation:
The 4 is in the hundred thousands place hope i helped
Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5
