A nonlinear equation may not have fewer than two degrees. Linear equations are useful for professional and personal settings, but they may be easier to use for personal application than nonlinear equations.
These are some examples of situations in which you may want to use linear equations:. You may use a linear equation to determine variable costs. In this situation, x would represent the number of square feet you need painted, and this is the linear equation you could use:. You may want to use linear equations to determine which rate is better in a scenario.
For example, you may be considering hiring a catering service for an important party. This is the linear equation to determine the price for the first company:. This is the linear equation to determine the price for the second company:.
By using these linear equations, you can determine that the first company may be cheaper and decide which company you prefer to hire based on the price. You may want to use linear equations for determining earnings. For example, an agent for a local band is trying to determine how much they may earn from an upcoming performance.
This means the agent may use this linear equation with y representing the earnings and x representing how many tickets they can sell:. By using this linear equation, the agent can input different values in for x to learn how many tickets they need to sell to reach profit goals for the performance. Professionals may use nonlinear equations more often than linear equations in various professional settings. These equations can be useful for project management and making predictions.
These are some examples of nonlinear equations:. Regression analysis is a statistical technique that professionals can use to study the relationship between variables of interest.
Though you can use regression analysis with linear equations, you can also use it with nonlinear equations. You can also use it to make predictions and estimate effects. There are many nonlinear equations for regression analysis, and this is one you can use:.
A logarithmic scale is a nonlinear equation that shows exponential growth on a graph. Professionals use logarithmic scales in many fields, like actuarial science, medicine, archeology, mathematics, forensic science, finance and geology. You can use this scale to prevent large values from skewing the data on a graph and to show multiplicative factors or perfect changes. Understanding the difference between linear and nonlinear equations is foremost important.
Here is the table which will clarify the difference between linear and nonlinear equations. So let us understand what are linear and nonlinear equations exactly. Linear Equations. Non-Linear Equations. A Linear equation can be defined as the equation having the maximum only one degree. A Nonlinear equation can be defined as the equation having the maximum degree 2 or more than 2.
A linear equation forms a straight line on the graph. A nonlinear equation forms a curve on the graph. The general form of linear equation is,. Where x and y are the variables, m is the slope of the line and c is a constant value. The general form of nonlinear equations is,. Popular Algebra Links.
