Please explain and give an example:

Solving linear and quadratic equations.

Please type answer do not hand write. Thank you.

Expert Solution

A Linear equation have the form like following.

Here are variables having power one.

The simplest linear equation is ax+b = 0

the solution is x = -b/a and a is not equal to zero.

where a, b are constants.

to solve linear equation means we have to find unknown values. we require n equations if there are n unknown varibales.

The equation of line y = mx+c is the example of linear equation.

Quadratric equation is defined as

Here the unknown varibale x has highest power 2. here a is not equal to zero. if a =0, then equation becomes linear equation.

we can solve the equation as follows.

Hence The quadratic equation has two solutions.

and

The equations of circle, ellipse, parrabola are examples of quadratic equation.

Circle equation

where (a,b) the co-ordiantes of center of circle

and r is the radius of the circle

18.11 Lab: Linear diophantine equations In this program, you will be solving linear Diophantine equations recursively. A linear Diophantine equation is an equation in the form: ax + by = c where a, b, and c are all integers and the solutions will also be integers. See the following entry in Wikipedia: Linear Diophantine equations. You will be solving this using the recursive version of the Extended Euclidean algorithm for finding the integers x and y in Bezout's identity: ax...

This is a question about Ordinary Differential Equations. For solving linear differential equations, I have seen people use the method of integrating factors and the method of variation of parameters. Is it true that either of these 2 methods can be used to solve any linear differential equation? If so, could you show me an example where a linear differential equation is solved using both of these methods. If not, could you explain using examples as to why this is...
