Trigon” is Greek for the triangle, and “metric” is Greek for measurement. The trigonometric ratios are special measurements of a right triangle (a triangle with one angle measuring 90°). Remember that the two sides of a right triangle which form the right angle are called the legs, and the.....

### Sexagesimal, Centesimal and Circular Systems

Sexagesimal, Centesimal and Circular Systems We know, Sexagesimal, Centesimal and Circular Systems are the three different systems of measuring angles. Sexagesimal system is also known as English system and the centesimal system is known as French system. There are three systems of measurement of.....

### Prove – Radian is a Constant Angle

Radian is a Constant Angle Radian is a unit of angle, the degree being the other unit. When a particle makes or completes one complete revolution, the angle swept by the particle is 360oo or 2π2π radians. Any quantity is said to be completely defined when it is expressed in terms of magnitude a.....

### Important Properties on Circle

A circle is a line forming a closed loop, every point on which is a fixed distance from a center point. Center is the point inside the circle. All points on the circle are equidistant (same distance) from the center point. The radius is the distance from the center to any point on the circle. [&h.....

### Sign of Angles

Sign of Angles An angle is made up of two rays with a common endpoint. This endpoint is the vertex of the angle. The angle symbol is a mathematical symbol that is placed ahead of character s, usually uppercase italic letters representing spatial points, to describe a geometric angle formed by the.....

### Antilogarithm

In mathematics, logarithms were developed for making complicated calculations simple. In mathematics, the logarithm is the inverse operation to exponentiation, just as division is the inverse of multiplication and vice versa. That means the logarithm of a number is the exponent to which another f.....
