Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments. In simple words, Simple interest represents a fee that you pay on a loan or income that you earn on deposits. … [Read more...]

## Midpoint Formula

Sometimes while solving maths problems you need to find the midway between the two points. For example, you might need to find a line that bisects a given line segment. This middle point is called the "midpoint". From a numerical point of view, the midpoint of a segment can be considered to be the average of its endpoints. This concept helps in remembering a formula for … [Read more...]

## Volume Formula

Volume is the quantity of 3-D space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic meter. … [Read more...]

## Trigonometric Identities

In mathematics, Trigonometric Identities are equalities that have a trigonometric function and are true for every value of the occurring variables where both sides of the equality are defined. Geometrically, these are identities having specific functions of one or more angles. They are somewhat similar to triangle identities, which are identities potentially having angles but … [Read more...]

## Circumference Formula

The Circumference of a Circle is the distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. The word circumference is used when we are measuring physical objects, as well as when considering abstract geometric forms. … [Read more...]
