There isn't one. If you're entering a complex number in rectangular form, separate the real and imaginary parts with a comma (left of the 4). If you're entering a complex number in polar form, separate the magnitude and the angle with the angle symbol (2nd comma).

I have a ti3 and ti 86 but not got intructions for ti86 and was considering getting ti92 but not sure if the ti 92 is any better than what i have


That depends on what you need to do with the calculator. The TI-83 is better at some things, the TI-86 is better at some other things, and the TI-92 is better at yet other things.
The 83 and the 86 both use the Z80 processor, though the 86 is quite a bit faster. The 92 uses a 68000 processor. Though the 83 has a faster processor than the 86, the 86 has some additional calculus capabilities.
You can download TI's manuals from their support website.
There's a good comparison of present and past models here.

What is the different between ti-86 and ti-83


The 86 has more memory. It also has some advanced calculus capabilities the 83 doesn't. However you're much more likely to see examples for the 83 in textbooks and other references.
