Answer:
Step-by-step explanation:
sin(0) = 0/2
sin(30) = 1/2
sin(45) = [tex]\sqrt{2}[/tex]/2
sin(60) = [tex]\sqrt{3}[/tex]/2
sin(90) = [tex]\sqrt{4}[/tex]/2
cos(90) = 0/2
cos(60) = 1/2
cos(45) = [tex]\sqrt{2}[/tex]/2
cos(30) = [tex]\sqrt{3}[/tex]/2
cos(0) = [tex]\sqrt{4}[/tex]/2
notice that sin and cos repeat, but in reverse
the answer for your questions is in there.
