WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships … WebWe can easily compute the sines and cosines for certain common angles. It is found in an isosceles right triangle, that is, a 45°-45°-90° triangle. any right triangle c2 = a2 + b2, but in this one a = b,so c2 = 2a2. Hence c = a√2. Therefore, both the sine and cosine of 45° equal 1/√2 which may also be written √2 / 2.
