- In particular, you can directly find the sines and cosines for the angles 30°, 45°, and 60°. Ptolemy knew two other angles that could be constructed, namely 36° and 72°. These angles were constructed by …
- The cosine of an angle, ?, defined with reference to a right angled triangle is cos ( ? ) = adjacent side hypotenuse = b h . The cosine of a complex argument, ?, is
- Finding sines and cosines of special angles. We have already learned some properties of the special angles, such as the conversion from radians to degrees.
- Cosines Definition of cosine The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°.
