You have to put the equations into matrix form first. To do this, each variable has one column in the first matrix and you fill in the co-efficients for the variables. The second matrix has one column and contains all the numbers.

{ 2 -1 1 -1} = Matrix A

{ 1 3 -2 0}

{ 3 -2 0 4}

{-1 -3 -3 -1}

{-1} = Matrix B

{-5}

{ 1}

{-6}

{x=-2} = A*(B^-1)

{y=-.2}

{z=3}

{w=1/6}

I used excel for all my calculation and a helpful tutorial can be found here. I hope this helps and have a nice day!

You can calculate first derivatives of some functions at given points; you can calculate definite integrals over a given interval, but you cannot solve differential equations.

There is nothing to solve here.You just have an expression with two letters; you have no equation to solve because you need an = sign.

See if it has an equation mode, and select quadratic equations. If it has a SOLVE feature, enter equation, provide a guess and solve.

deSolve( ) solves differential equations. The general syntax is deSolve(1stOR2ndOrderODE, Var, depVar). The first argument must be a first order or second order differential equation, the second argument is the independent variable, and the third is the dependent variable (the name of the function you are trying to obtain.)

Your command does not have a differential equation, and it does not have the dependent variable.

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:Putting y - vx

Since y is a function of x so is v

Separating the variables

Integrating

Substituting (12) in equation (10)

I assume that if you want to input the equation it is with the intent to solve it. If that be the case then what follows will help you input and solve any equation (linear, quadratic, trig, etc.)

Make sure the calculator angle unit is the same as your problem requires (degree, radian, grad). Here are some screen capture to help you. Change the equation to yours.

To enter the equation in screen above, use the right arrow.

You have to enter an initial guess on line X=, a default value may be supplied by calculator: It depends on last value stored in X. Once a value is entered press the F6 key to SOLV

Press F1: Rept if you want to solve another equation.

You did not provide a general (n) term. However, I figured it to be something involving n^2. Hence the sum to n terms can be of the form: xn^3 + yn^2 + zn. Using the partial sums: 1, 6 (1+5), and 18 (1+5+12) we can build a linear equations system:

1= x + y +z (n=1)

6 = 8x + 4y +2z (n=2, n^2=4, n^3 = 8)

18 = 27x + 9y + 3z (n=3, n^=9, n^=27)

Solving for x,y,z we get x = 1/2, y= 1/2, z =0

Hence 1+5+12+22+..+ f(n^2)= 1/2(n^3+n^2)

1= x + y +z (n=1)

6 = 8x + 4y +2z (n=2, n^2=4, n^3 = 8)

18 = 27x + 9y + 3z (n=3, n^=9, n^=27)

Solving for x,y,z we get x = 1/2, y= 1/2, z =0

Hence 1+5+12+22+..+ f(n^2)= 1/2(n^3+n^2)

And your question is? If you just want to know how to solve this system, you only need to substitute one equation into the other and solve for the remaining unknown.

y=3x (equation 2), so plug it into equation 1

7x-2y=1

7x-2(3x)=1

7x-6x=1

x=1

from equation 2 then, you know y=3x=3

y=3x (equation 2), so plug it into equation 1

7x-2y=1

7x-2(3x)=1

7x-6x=1

x=1

from equation 2 then, you know y=3x=3

Just plug in one side of the equation and find the answer. Then plug in the other side and compare answers.
