Trigonometry is the branch of mathematics that deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles. The relationship is presented as the ratio of the sides, which are trigonometric ratios. The six trigonometric ratios are sine, cosine,...
which was published in the 11thcentury, includes the general law of sine. Nasīr al-Dīn al-Tūsī later stated the plane law of sines in the 13thcentury. In his book,On the Sector Figure, he wrote the law of sines for plane and spherical triangles, provided with proofs. ...
In mathematics, an "identity" is an equation which is always true, regardless of the specific value of a given variable. An identity can be "trivially" true, such as the equationx=xor an identity can be usefully true, such as the Pythagorean Theorem'sa2+ b2= c2 ...
sin(x) is the ratio of the side opposite the angle and the hypotenuse, cos(x) is the ratio of the side adjacent to the angle and the hypotenuse, tan(x) is the ratio of sine and cosine Where is trigonometry used in real life? In real life, trigonometry has applications in many ...
