Answer:
15-9 will be greater
Step-by-step explanation:
Caroline wants to compare the expressions 15-9 and 9 (-15)
For us to know the result that is greater, we will have to check if the first value is less than or greater than the other. For example
If for a-b
a-b is greater if a>b
a-b is lesser if a<b
Given 15 - 9
Since 15 > 9, this means that 15-9 will be greater compare to 9-15
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
