What are the six steps to solving an equation


I am sorry, the question is too general. Some equations do not require that many steps. And there is quite a few types of equations. You will have to be more specific. Try again.

I want to solve an complex equation on casio fx-570 ES Plus


Your scientific calculator is unable to solve complex equation with complex coefficients. You should try to solve by hand directly using the quadratic formula or by factoring the polynomial in z
failing that, another way would be to set z=x+iy, substitute this for z, carry out the algebra and try to separate real and imaginary parts. But your two equations will constitute a system of two quadratic equations. I am not aware of any general method to solve coupled nonlinear equations.
Good luck.

How to use casio 9850GC PLUS to solve equations in polar form?


Put the calculator in Equation solving mode. Select F3:Solver. Enter your equation; use X as unknow (no need to use Theta, the name of the variable is irrelevant.) Besides if you use theta you will get a syntax error.

How to find values of x in higher order equations(above cube) on casio 570 ES?


In equation mode, you have system of linear equations (3 unknown) you have polynomial (quadratic and cubic), and solver. Use the solver foe any type of equation (nonlinear, polynomial of order higher than 4, trigonometric, exponential, logs).

How can i set up and solve n+2n-3000


If you call one n (as you did), the other is 2n-3000. The sum of the two is 91500. Thus
2n+n-3000=91500. Combine the terms with n to get 3n, Add 3000 to both sides (members) of the equation. Finally
3n=91500+3000=94500 . Divide both members by 3 to get
n=94500/3=31500
The other is 2n-3000=2(31500)-3000=60000.
Some calculators have a solver that you can use to solve linear and nonlinear equations, However, since you no not disclose the brand or model number, nobody will be able to tell you how to set it up. Sorry.

Examples of homogeneous differential equation


Hi janeth sabay,

 

Have a good day!!

 

Here is your needed example for Homogenous differential equation:

 

The equation 49e8abf8a1c5be91fadbf33a5405bdc3.gif is said to be homogeneous if P and Q are homogeneous functions of x and y of the same degree.

cc966bdc4bb845d781e46c1ccf986b02.gif(1)

We can test to see whether this first order equation is homogeneous by substituting 21fe29cd49ecbd3abe2ae6373e89eab6.gif . 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 1:19c981882c1f9b05fadf586b56a931bc.gif(2)

d8be3b3ee65102c9f51076f6fbf371a4.gif(3)

There are no terms in x on the right hand side and the equation is Homogereous.Example 2:72f80f87eb510a9e0fd81c423b3faa55.gif(4)

b8821dedcc10e7738d072f6f0e2b7585.gif(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:

fa23f299c6866eb1139d14429d91ce12.gif(6)

Putting y - vx

Since y is a function of x so is v
