Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
Answer:
.12
Step-by-step explanation:
First set up your proportion.
Multiply 3 and 25 by 4 to get 12 and 100.
the answer would be 12 hundredths or .12

-4, -5/6, 3/7, 0.7 is least to greatest
Y=1/3x-2
3y=x-6
3y-x=-6
y=1/4x+11
4y=x+44
4y-x=44
