The values of sine and cosine of 30 and 60 degrees are derived by analysis of the equilateral triangle. In an equilateral triangle, the 3 angles are equal and sum to 180°, therefore each corner angle is 60°. Bisecting one corner, the special right triangle with angles 30-60-90 is obtained.
8 paź 2024 · You can find exact trig functions by typing in (for example) "cosecant 135 degrees" into any search engine.
23 cze 2011 · I solved all sines and cosines values for angles from 1° to 90°. For angles that are multiples of 3, the solutions are expressions of real number. For all angles that are not multiples of 3, the solutions are expressions of complex numbers, strictly speaking, is the sum of 2 conjugate imaginary numbers.
