Question

what is sin π / 2 +thita​

Answer 1

Answer:

sin(π/2 - θ) = sin(π/2 + θ) can be interpreted as saying that the sine function has mirror symmetry about the line x = π/2, which I think you'll agree is the case. Comment on Howard Bradley's post “Yes, it does mean that. sin(π/2 - θ) = sin(π/2 + θ...”

Answer 2

Answer:

sin 90+thita = cos thita
