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:
Step-by-step explanation:
Refer to file. Trying something different. Should be easier to read than text format and is easier than mathML.
Answer:
I need help with this too
Step-by-step explanation:
The equations will only have one solution because they have different slopes and also next time use desmos for those kinds of problems it’ll always help
To simplify combine like terms:
8m + 7m = 15m
4n - 2n = 2n
Simplified: 15m + 2n
