WebbIn Trigonometry, different types of problems can be solved using trigonometry formulas. These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc. Some formulas including the sign of ratios in different quadrants, involving co-function identities (shifting angles), sum & difference … WebbPremature rounding caused a significant number of candidates to lose at least 1 accuracy mark, notably with a solution of 0.28 c instead of 0.27c. 2.
