sin pi by 2 minus theta In 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
Explanation using appropriate Addition formula sin A B sinAcosB cosAsinB hence sin 2 sin 2 cos cos 2 sin now sin 2 1 and cos 2 0 hence sin 2 cos cos 2 sin cos 0 sin 2 cos Answer link iOS Yes cos theta sin frac pi 2 pm theta always holds You can easily prove by trigonometric rules but you can also easily check by graphical observation and symmetry
