Now the key turn: equal range does not mean equal height. Thirty and sixty degrees are complementary; their sum is 90 degrees. Sin 60 equals sin 120, so both have the same range. Twenty and seventy degrees do too. In general, complementary angles satisfy theta one plus theta two equals 90 degrees, and R of theta equals R of 90 minus theta. But their vertical components differ. Since sin 60 is greater than sin 30, maximum height at 60 degrees exceeds maximum height at 30 degrees. The 60-degree path rises higher, although both land at the same horizontal position. For JEE: 30 and 60 have equal range, with lower and higher heights; 45 has maximum range and intermediate height in this comparison. Keep maximum height proportional to sin squared theta. So, does the higher throw always go farther? No. The 30-degree and 60-degree balls travel the same range, but the 60-degree ball rises higher.
