Question

explain trignometry formulae​

Answer 1

Step-by-step explanation:

concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure. For example, the triangle contains an angle A, and the ratio of the side opposite to A and the side opposite to the right angle (the hypotenuse) is called the sine of A, or sin A; the other trigonometry functions are defined similarly. These functions are properties of the angle A independent of the size of the triangle, and calculated values were tabulated for many angles before computers made trigonometry tables obsolete. Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures.

Answer 2

Take any triangle ABC:

Apply pythagoras theorem,

Then get

AB2 + BC2=AC2

Then divide it by AB2

then we get

AB2÷AB2+BC2÷AB2=AC2÷AB2

1 + tan thetta = sec thetta

Do same for other
