List of Maths Words That Start With L With Definitions and Examples
Can you remember any Maths term which starts with the letter ‘L’? There are several such terms in Mathematics; for example, line, length, least common factor, and many more. These terms are important and one must know about the meanings of these terms. Therefore, in this article, we have provided you with a list of words starting with the letter ‘L’ along with their Mathematical meaning.
List of Maths Terms Starting with ‘L’
Given below are some of the important Mathematical terms starting with the letter L. Knowing these terms will help you to understand the concepts of Mathematics easily.
Least Common Denominator: The least common denominator (LCD) can be defined as the smallest number which is also a common denominator for a given set of fractions. It is also known as the lowest common denominator.
Least Common Multiple (LCM): The least common multiple of a set of integers is the smallest integer that is an exact multiple of every number in the set.
Least Upper Bound: The least upper bound of a set of numbers is the smallest number that is larger than every member of the set.
Legs of a Right triangle: The two sides that are not the hypotenuse. The legs are the two sides that are on either side of the right (90 degrees) angle.
Length: The straight line distance between any two points.
Less Than: Having a smaller value than the given.
Line: Line can be defined as the distance between two points and is represented by joining the two points.
Line Graph: It is a diagram showing a system of connections or interrelations between two or more things by using lines.
Line Segment: It is a piece of a line with endpoints at both ends.
Line Symmetry: If a figure is divided by a line and both divisions are mirrors of each other, the figure has line symmetry. The line that divides the figure is the line of symmetry.
Linear: An equation or graph is linear if the graph of an equation is a straight line.
Linear Function: A function of the form f(x) = mx + b where m and b are some fixed numbers. The names “m” and “b” are traditional. Functions of this kind are called “linear” because their graphs are straight lines.
Linear Regression: An attempt to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered as the independent variable, and the other is considered as the dependent variable.
Locus: The set of all points meeting some specified condition.
Logarithm: The exponent of the power to which a base number must be raised to equal a given number.
Long Division: In Maths, long division is a method used for dividing large numbers into groups or parts. The long division helps in breaking the division problem into a sequence of easier steps. Just like all division problems, a large number, which is the dividend, is divided by another smaller number, which is called the divisor, to obtain a result called the quotient and sometimes a remainder.
We hope this list has helped you learn about some important Mathematical terms and their meaning. There are a lot more terms that start with the letter L. We advise you to go through these terms regularly to be familiar with their definitions and meanings.
FAQs on Words and Terms That Start With L in Mathematics
1. What is a line in mathematics?
A line is a straight one-dimensional figure that extends infinitely in both directions without endpoints.
- It has no thickness and no endpoints.
- It is usually represented with arrows on both ends (↔).
- It can be named using two points, such as line AB.
- The equation of a line in coordinate geometry is often written as y = mx + c.
2. What is a linear equation?
A linear equation is an equation of degree 1 that forms a straight line when graphed.
- Standard form in one variable: ax + b = 0
- Slope-intercept form: y = mx + c
- Example: 2x + 3 = 7
- Solution: 2x = 4, so x = 2
3. What is the least common multiple (LCM)?
The least common multiple (LCM) is the smallest positive number that is divisible by two or more given numbers.
- Find prime factors of each number.
- Take the highest power of each prime.
- Multiply them together.
- Example: LCM of 6 and 8 = 24.
4. What is a logarithm in mathematics?
A logarithm is the power to which a base must be raised to obtain a given number.
- General form: logba = x means bx = a
- Example: log10100 = 2
- Common logarithm has base 10.
- Natural logarithm has base e.
5. What is a limit in calculus?
A limit is the value that a function approaches as the input approaches a specific number.
- Written as: limx→a f(x)
- Example: limx→2(x²) = 4
- Limits are fundamental for defining derivatives and integrals.
6. What is lateral surface area?
The lateral surface area is the area of all the sides of a solid figure excluding its base(s).
- For a cube: 4a²
- For a cylinder: 2πrh
- It does not include the top or bottom faces.
7. What is a line segment?
A line segment is a part of a line that has two fixed endpoints.
- It has a definite length.
- Named by its endpoints, such as AB.
- Distance formula in coordinate geometry: √[(x₂−x₁)² + (y₂−y₁)²].
8. What is a locus in mathematics?
A locus is the set of all points that satisfy a given condition.
- Example: The locus of points equidistant from a fixed point is a circle.
- It is widely used in coordinate geometry.
- Locus problems often involve distance or angle conditions.
9. What is a leading coefficient?
The leading coefficient is the coefficient of the term with the highest power in a polynomial.
- Example: In 4x³ − 2x + 7, the leading coefficient is 4.
- It determines the end behavior of the graph.
- Important in quadratic and higher-degree polynomials.
10. What is the least squares method?
The least squares method is a statistical technique used to find the best-fit line by minimizing the sum of squared errors.
- Equation of best-fit line: y = mx + c
- Minimizes Σ(observed − predicted)²
- Commonly used in regression analysis and data modeling.
