Math Terms StartingWith H

In this page math terms startingwith h we are going to see definitions of mathematical terms starting with the letter "H". We have listed out almost terms in math starting with H.In math also it is very important to know the meaning of many important words which are being used in the subject math.Each term is defined and examples are provided where ever it is necessary. Links are given for every words, by using this students can learn the meaning and its application more clearly.Here are the math terms startingwith H.



Half turn

 A 180° turn as from front to back and viceversa.


Hectare is a metric unit area defined as 10,000 square meters.


Vertical distance from base to the top.The another name of height is altitude.


Half of the sphere.


A polygon with 7 sides and 7 angles.


A six sided polygon.


Histogram is a graphical representation in statistics. It shows the visual impression of the distribution data. It groups numbers in to ranges.


Right angles to the vertical or parallel to the level ground. In graph paper x-axis is refer to the horizontal line. In the diagram below the line x = 1 is parallel to x axis.


One type of conics is hyperbola. Hyperbola is a set of points found by keeping the difference of the distances from two points is constant.


The side opposite to the right angle in right angled triangle. Hypotenuse is the longest side of the right angled triangle.


An assumed statement used as a premise in an argument.

Half angle formulas

In trigonometry we have half angle formulas.

  • Sin A = 2 Sin (A/2) cos (A/2)
  • Cos A = cos² (A/2) - Sin² (A/2)
  •  tan A = 2 tan (A/2)/[1-tan² (A/2)]
  • Cos A = 1 - 2Sin² (A/2)
  • Cos A = 2Cos² (A/2) - 1
  •  sin A = 2 tan (A/2)/[1+tan² (A/2)]
  • cos A = [1-tan²(A/2)]/[1+tan² (A/2)]
  •  sin²A/2 = (1-Cos A)/2
  • Cos²A/2 = (1+Cos A)/2
  •  tan²(A/2) = (1-Cos A)/(1+Cos A)

Heron's formula

To find the area of triangle when measurements of three sides are given.

Area of scalene triangle =


Here a, b and c are the sides of the triangle and s is known as perimeter of the triangle. To find the value of s we have to use the formula

 S = (a + b + c)/2

Harmonic mean

This  is nothing but the reciprocal of the arithmetic mean of the reciprocals of the given numbers.

In other words to find the H of the given numbers, we have to divide n (total number of given numbers) by the sum of the reciprocals of the given numbers.

Hour clock arithmetic

If the divisor m=12, then the arithmetic modulo 12 is called the clock arithmetic. The remainder can be related to hour numbers in a clock where 0 corresponds to the 12 hour.

A function of several variables is said to be homogenous of degree n if each variables are multiplying by t has the same effect as multiplying the original function by tⁿ.That is f(t x, t y) = tⁿ f(x,y)

These are the word in math terms startingwith h.
