In a market…
Vendor: How many kilos of apples, sir?
Customer: 3x-5: where x = 6!
Vendor: Okey! 13 kilos. Oh! It’s $ sin90° per kilo!
Customer: Uhmm… Can you convert that to arctangent?
Vendor: Sorry! I can’t! Let’s just use tangent, okey? So $ sin90° equals... It’s $ 5tan45°! If you want, you can apply reduction formula.
Customer: No, Thanks! Here’s (x²-4x-3)/sin3x; where x = $7.00. Keep the change!
If this is how useful mathematics is in our daily lives...

Let’s fight! C’mon! #(ð_6)
