Question about TI-89 Calculator
...example when I input: d(x^2,x) it outputs "2." instead of the expected 2x also, if I integrate: S(x,x) it outputs ".5" instead of x^2/2 Probably a value stored in the "x" variable (guessing x=1) try ...
...example, how do I plot y = 2t2 + 20t I am used to situations where y = f(x) What is the best window setup? Hi, The symbol t is what is called a dummy variable, it could be anything. Use variable X, ...
it keeps sasying err: windows everytime i try to graph something There's a problem with your window variables, for example, Xmax <= Xmin. Press the WINDOW key and check your variables
...example 2x^4+3x^2. I press home, f3, and input my equation, ,x and then press enter. instead of the solution coming out to be 8x^3+6x, the solution comes out as 8060... how can i fix this? You have ...
when i am inputting an equation how do I put in the variable (y for example): 1-2/3y=9/5-1/5y+3/5 on the calculator press y= at the top of the calculator and use the variable button2nd row 2nd button.
...example: I enter FACTOR(x^3-5xx) and the answer comes up as (2.)^2(3.) You apparently have a numerical value stored in the variable "x" and the calculator is using that value. To get rid of it, press ...
...example, I write: 3x+3x and that result is 0? How come? Shouldn't it be 6x? This calculator cannot do algebra ( manipulating expressions with letter symbols) . It does not have a CAS (computer ...
