We all know that calculators have pre-installed general equations which give output basis on the inputs of the equation. The results are quicker and have fewer errors as compared to human solving the equation.

Similarly, solving equations on computers is faster and even have fewer errors as compared to calculators. Computers can perform multiple functions, whereas the latest calculators are limited to a few.

What is linear and non-linear equation?

Sometimes remembering the definitions can be a really hard task, at such times remembering small indicators is beneficial. How I remember the linear and non-linear equation is through their graphs.

Linear equations look like a straight line when sketched, whereas non-linear equations look like a curve. Linear equations have a constant slope, whereas non-linear equations have a variable slope. Furthermore, the output is directly proportional to its input for…
