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
Answer: c and e
explanation: put the equation in the graphing calculator and look at the graph and table the answer will show
Answer:
-21
Step-by-step explanation:
3x7=21 and a negative x a positive is always negative
Draw a cartesian graph and draw the points in , then see where c should be to get a right angled triangle
