Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
Answer:
the last one
Step-by-step explanation:
2-3x=-x-8
-3x=-x-10
-2x=-10
X=5
Answer:
-10,-100,-8,-7,-2,-4,-5,-20,-6,-3,-7
It would be 4.05 because the 1 is lower so it is rounded down
