Free master classes of mathematics

In this class we will study about Trigonometry from basic to advance level, Height and distance from basic to advance level. We  will learn what was the need of these concept. Why scientist discovered these concepts. I will solve your queries if you have any one regarding the subject. Trigonometry conept are very helpful in our daily life. If we consider these things we can calculate any height of an object and its distance. Basically, trigonometry is the branch of mathematics 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, cosine, tangent, cotangent, secant, and cosecant. These six trigonometric functions in relation to a right triangle. 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 is called sine of A
