Solving Line Integrals with TI-89 Emag Program

[yugoo]

Hi, i was just wondering that if someone has this program called Emag for their ti 89 titanium. I can't seem to make this program work properly. This is from the symbulator site. It is for integrals, curls, gradients etc. I couldn't get the progam to work properly. I tries to do this example:

For F=[y,-x,o] in cartesian, evaluate the line integral F*dl along the path defined by
y=2x and z=4x, between the points (0,0,0) and (1,2,4)

F2 lines([y,-x,0])
choose rect
integration variable x
x initial = 0
x final = 1
y= 2*x
z = 4*x
F5 [enter]
answer is zero

but was unable to go after the step of F2 lines..., i don't know what they mean when they say choose rect. Are there any compatability issues,since the program was made for 89 not 89 t. Any help will be appreciated . Thanks

Hi there! It sounds like you're having some trouble with the program. I'm not familiar with Emag, but it looks like you need to select a rectangular path in order to evaluate the line integral. Once you've done that, you need to define the parameters of the rectangular path. The example you provided looks like it involves setting the integration variable as x, the initial value as 0, the final value as 1, and then inputting the equations for y and z. After you've done that, press F5 to evaluate the integral.

If you're still having trouble, it might be worth looking into whether there are any compatibility issues between the program and the TI 89 Titanium. Hopefully that helps!

I am not familiar with this specific program and its compatibility with different calculators. However, I can provide some general advice for solving line integrals using a TI-89 calculator.

Firstly, it is important to ensure that the program is compatible with your specific calculator model. If the program was designed for the TI-89 and you are using a TI-89 Titanium, there may be compatibility issues that could prevent the program from working properly.

Secondly, when using a program to solve line integrals, it is important to carefully input the correct parameters and functions. In this case, it seems that the program is asking for the path to be defined in terms of x, y, and z. However, the example given only provides equations for y and z in terms of x. It may be necessary to input the function for x as well in order for the program to work properly.

Additionally, when the program asks for "choose rect," it is likely referring to choosing the rectangular coordinate system. This may be necessary for the program to properly evaluate the line integral.

In general, it is always a good idea to carefully read through the instructions and make sure all parameters are correctly inputted when using a program to solve mathematical problems. If you continue to have difficulties, it may be helpful to consult the program's user manual or seek assistance from the program's developer.
