Answer:
It is an identity, the proof is in the explanation
Step-by-step explanation:
csc(A)-cot(A)=tan(A/2)
I'm going to start with right hand side
tan(A/2)=(1-cos(a))/(sin(a)) half angle identity
tan(A/2)=1/sin(a)-cos(a)/sin(a) separate fraction
tan(A/2)=csc(a)-cot(a) reciprocal and quotient identities
2/15
4/5-2/3
convert so they have the same denominator
12/15-10/15
solve
2/15
The volume of the cylinder would be:
282.74
8/10 of the students in the art class are painting.
1/2=5/10
5/10+3/10=8/10
4 cupcakes because if you do 12/ 1/.. you do kcf = to 12 x 1/3= 4
