Question about Texas Instruments TI-89 Calculator
For example when I input:
instead of the expected 2x
also, if I integrate:
instead of x^2/2
What you do is go to the home screen and hit f6 and hit 'clear a-z' that will clear all variables from being numeric variables.

Probably a value stored in the "x" variable (guessing x=1)
try the following, type or look for the "Define" function: Define X=X and see what happens, also try Cleaning the variables "F6>cleanup, etc" as a last resource do factory reset, but first archive your important files (not very recomended as some of them may contain the variable's value and just not solve this)

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)
