Hi janeth sabay,

 

Have a good day!!

 

Here is your needed example for Homogenous differential equation:

 

The equation is said to be homogeneous if P and Q are homogeneous functions of x and y of the same degree.

(1)

We can test to see whether this first order equation is homogeneous by substituting . If the result is in the form f(v)i.e. all the x's are canceled then the test is satisfied and the equation is Homogeneous.

Example 1:(2)

(3)

There are no terms in x on the right hand side and the equation is Homogereous.Example 2:(4)

(5)

So the original equation is not homogeneous.Methods Of Solution.

A solution can be found by putting y = vx on both sides of the equation:-

Example 3:

(6)

Putting y - vx

Since y is a function of x so is v

(7)

Separating the variables

(10)

Integrating

(11)

(12)

Substituting (12) in equation (10)

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

This calculator doesn't really support a solver like that. You can use Woflram Alpha to solve equations like that really quickly. Example
There are more expensive calculators that will solve these types of equations, but I would recommend just using Wolfram Alpha whenever you need a solution to a math problem.

The site seems to eat the plus signs I enter, so I will use PLUS to symbolize addition.

To find the equation of the straight line (y = a*x PLUS b) that passes through two points P1(x1,y1) and P(x2,y2) , you need to use
1. the coordinates of the points to calculate the slope a (gradient) as a=(y2-y1)/(x2-x1)
2. Replace the calculated value of a in the equation and write that one of the points ( P1(x1,y1) for example) satisfies the equation. In other words y1=a*x1 PLUS b.
Here y1 and x1 are known values, a has been calculated, and only b is still unknown. You can now use the equation y1=a*x1 PLUS b to calculate b as
b=(y1-a*x1)

Example: Equation of the line through (1,5) and (3,6)
Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2
The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=(1/2)*3 PLUS b.
Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5
Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2

I trust you can substitute you own values for (x1,y1, x2,y2) to duplicate the calculations above.

This expression 5x^2+15x+3 is not an equation, therefore it can have any value depending on the value of x. You have to make it an equation before looking for the particular value of x that satisfy your equation 5x^2+15x+3 =0

This calculator cannot solve equations because it does not have an equation solver.

Use the ^ key, located just above the divide key. For example, to calculate two to the fourth power, press 2 ^ 4 ENTER

Perhaps you have some data stored in the x variable.

With the calculator on, press [2nd] then the minus button. This brings up a list of all the saved data in the calculator. Look through the far left column of the list for x.

If you find x in the list, highlight x, then press F1, and then select delete.

Now it should work like normal.

use mr dvd discs-dvdr youcan buy at poundland they are the only discs that seem to work

I reset my calculator and this solved the problem. To reset your calculator press [2nd], then [6] (Mem), press F1 (reset), Select 3 for all memory, and select Yes.
