Arre, sin, cos, tan being ratios is the real thing, not just calculator buttons! If you just see them as buttons, you'll never understand *why* the answer is coming. In our Math class, Sharma sir took us outside to measure the school flagpole's height using a clinometer and these ratios. When you calculate it yourself with a triangle, the formula *yaad* rehta hai. For boards, they can ask the proof, not just the value.
