how do I use the solve function in program
I have a ti-89 titanium, and I am having trouble using the solve function in it. The program starts off asking for 5 variables such as x1, x2, v0, etc; when I get to the point of the program where I need the solve function, I write: solve(equation1=equation2,t1) "litte arrow" t1. "Little Arrow is that storing variable sign which is the sto button on the calculator. Of course before I get to the solve function, I create t1 equaled to zero so that the ti variable exists before I try to use solve(). I have also tried to take off the "little arrow" t1 part of it on what I was trying to do but to no avail. Could someone help me out? If no one has understood what I was talking about, could someone please at least give me some example code that uses the solve function within it. Thank you.
