Explanation: I hope that the Problem is : Prove : cos2A1−tanA+sin3AsinA−cosA=1+sinAcosA. We have, cos2A1−tanA+sin3AsinA−cosA ,. =cos2A1−sinAcosA ... How can I solve sinA-cosA=1 where 0 degree<=A<=90 degree. Thank you. Nazrul,. One way to approach this problem is to use sin2A = 1 - cos2A and hence write. ‑‑cosa ‑sina O" ‑F"' ‑' cosct sina O‑ ‑F'‑ sinat ‑cosa O S + ‑sincr cosa O S. ‑ O O 1‑r‑‑1,2‑M. r‑lt2 . 0 O 1‑. r2 ‑M‑ r2. ‑"O 1 O‑‑F" ""P"‑. + ‑1 O O S +Q == O ...
