Question about Casio FX991ES Scientific Calculator
Set Input/output to MathIO.
Press the Integrate key, to the right of CALC.
The image of integral appears with a rectangle for the function, and two small squares (one for the upper limit the other for the lower limit).
Type in the integrand (the expression you want to integrate) in the bigger (on your display) rectangle. Use appropriate parenthesis. To type in X press [ALPHA] )
Use the down arrow to move cursor to the square for the lower limit. Type in the lower limit. Use the Up arrow to move cursor to the upper limit square. enter the upper limit. Press [=] key. If you did not make mistakes, and your expression is not too complicated you should get your integral.
Note: The screen captures are not from a Casio FX991ES. But that should not matter to you.

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.
Putting y - vx
Since y is a function of x so is v
Separating the variables
Substituting (12) in equation (10)
