Question

If alpha,beta,gamma,delta are the smallest positive angles in ascending order of magnitude

Answer 1

Answer:

Here you go ,

α,β,γ,δ are the smallest positive angles in ascending order of magnitude which have their sines equal to positive quantity λ. ⇒sinβ=sin(π−α) (As we know sine is positive in first and second quadrant and the angles is in ascending order, the order of ascending is α<β<γ<δ).
