Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.
Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.
Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7
Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18
Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.
Answer: 37,39,41,43
tan²(<em>x</em>) - sin²(<em>x</em>) = sin²(<em>x</em>)/cos²(<em>x</em>) - sin²(<em>x</em>)
… = sin²(<em>x</em>) (1/cos²(<em>x</em>) - 1)
… = sin²(<em>x</em>) (sec²(<em>x</em>) - 1)
… = sin²(<em>x</em>) tan²(<em>x</em>)
The first one for the first y-intercept number is -1.
The second one is 5. (Not negative)
The third one is 11 (Not negative)
The fourth one is just 11 (Not negative as well)
The ones that say Not negative means that those numbers are postive.
I hope this helps though! :D
