Answer to Problem 1RP

Solution:

In 5dxdt+5x2+3=0 ,

t is the independent variable and x is the dependent variable

And also a nonlinear equation.

Explanation of Solution

Given:

5dxdt+5x2+3=0

Calculation:

Independent and dependent variables:

If an equation involves the derivative of one variable with respect to another, then the former is called a dependent variable and latter an independent variable.

In the given equation t is the independent variable and x is the dependent variable.

Linear or nonlinear equation:

A differential equation is linear if it has the format as below,

anxdnydxn+an-1xdn-1ydxn-1++a1nxdydx+a0xy=F(x)

Where, anx,an-1x.,a0x and F(x) depends only on the independent variable x.

If the equation is not in the above format, then it is called nonlinear equation.

5dxdt+5x2+3=0 is the nonlinear equation, since it is not in the above format.

Hence, In 5dxdt+5x2+3=0 is,

t is the independent variable and x is the dependent variable

And also a nonlinear equation.

Final statement:

In 5dxdt+5x2+3=0 ,

t is the independent variable and x is the dependent variable

And also a nonlinear equation.
