Hello,
If I understand correctly you result do not display any decimal.
If you want a fixed number of decimal digits (exemple 2) Press the [MODE] key a number of times until you reach the screen that displays Fix Sci Nom and under them the numbers 1 2 3
Press 1 to choose Fixed format followed by 2 for TWO Digits
3 decimal digits [MODE] ---------[1 ] (Fix) 3
Hope it helps.

On my casio fx-83GT PLUS calculator whenever i use the inverse cos,sine and tan function math ERROR comes up how do i fix this


The inverse cosine function is defined for arguments from -1 to +1. 6 is outside of this domain, thus the error. Do you get an error if you try the inverse cosine of 0.6, for example?

If you're getting the same error for the inverse tangent, could you post an example?

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

I need straightforward key strokes for a casio fx115 es graphing calculator to solve linear equations. I have the Manuel but it only confuses me. this is an example of what I'm solving ...


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.

I'm just beginning to learn about trigonometric functions (sin, cosine & tangent). My math book says for a problem such as "4 cos 75.8", I should press 4, x, 75.8, cos, = (in that order)....


Try 4 x cos 7 5 . 8 =

The fx-300MS is a more advanced calculator than what the book is describing. It evaluates cosine(x) as cos x rather than x, cos.

Fractions


there is a A b/c button. This is the button use to enter fractions. so 4/3 would be entered as 4 |A b/c| 3

If you want to have the answers in fractions as well, then I believe you hit more a few times. And then there should be a display option, in the display option, there should be a b/c. This will show your answers in fractions. Hope it helps
