It's just the equation on the left being equivalent to the equation on the right by forming either counterpart using the other or obtaining an equivalent expression on both sides, correct? Is there a negative sign on the LHS? If not, I just obtain the equivalent expression of sin A cos A on both sides. Yes. And then we must express them in terms of the given values accordingly. That is not a minus Nobunaga Oda. Got it via equivalent expression of sin A cos A on both sides.
