MATH TERMS THAT START WITH Q

Quadrant :

A sector one quarter of a circle , or sector of a two dimensional Cartesian coordinate system.

Quadratic equation :

A polynomial with second degree is called quadratic equation.

General form of a quadratic equation is ax²+bx+c  =  0.

Here a, b and c are real numbers.

Quadrilateral :

A polygon with four sides and four angles. Square, rectangle, rhombus, parallelogram, kite, trapezium all are some forms of quadrilaterals.

Quadruple :

A number four times greater as another. That is to multiply or increase by four times.

Qualitative :

Descriptions or distinctions based on some qualities or characters.

Quantity :

A particular or infinite amount of anything.

Example :

A small quantity of milk.

Quarter :

One fourth of a quantity. One fourth of Canadian and American dollar. It has been written as 1/4.

Quartic :

Polynomial of degree 4 is called quartic.

Example :

4x⁴ + 3x³ + 2x² - 5x + 1

Quartiles :

In statistics, quartiles are the three points that divide the data into four equal parts. Median, lower quartile and upper quartile are those three points.

Quintic :

A polynomial(function) of degree 5 is called quintic function.

Example :

x⁵-x⁴- 2x³-x²+5

Quotient :

The result of division. The number of times one quantity is contained in another.

Example :

The quotient of of 6 divided by 3 is 2.

Quadratic Equation :

If the highest power of the variable in any equation is 2.Then we can that equation is quadratic equation. The general form of any quadratic equation is ax²+ bx + c = 0.

Quadratic Formula :

The formula to be used to solve the quadratic equation.

Quotient Rule :

This is the formula to be used to differentiate two x related functions which are multiplying.

(U/V)' =  [VU'-UV']/V²

Quintuple :

Multiplying any number by a factor of 5.

Quintiles :

From a set of data, the 20th and 80th percentiles are called the quintiles.
