Question

arccos[sin pi/6]
wouldnt that just be pi/6 right?

Answer 1

No, arcsin[sin pi/6] would = pi/6. First, determine sin pi/6

Answer 2

sin pi/6 is 30 deg....or 1/2? So would my answer be 1/2?

Answer 3

sin (pi/6) is sin(30)
sin(30)= 1/2

now find the
acos(1/2)
what angle gives you 1/2 when you do cos(A)

Answer 4

Now, you go for arccos(1/2)

Answer 5

hmmm.....so arccos 1/2 would be pi/3 correct?

Answer 6

Yes! You are understanding this!

Answer 7

Thank you so much!!!

Answer 8
