How to solve trig functions using ti-83 plus

Your best bet would be trying a math package on ti-calc.org - you can usually find something that does what you want there. You'll need a cable and the software to download these programs to your calculator. Here's a link to the trig section:

How do you convert decimal complex numbers in TI-84 (OS 2.53) to fractions?

I answered a similar question not long ago and here is what I wrote:

Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To convert a complex decimal value, that you just calculated, into a fraction use the command Math [1:>Frac] and it will convert the value to complex fractions
See below.

I suggest you upgrade the OS to version 2.55 MP.

How do I graph equations like x^2 + y^2 = 9 on my TI84 Plus silver calculator?

This is the equation of a circle centered on (0,0) and with radius r=3. You can draw it as a conic section.For that you will need the conics application. Look for it on education.ti.com
You can also draw it as two branches: y1=+ square root (9-x^2) and y2=-square root(9-x^2). The two parts may not overlap at the points on the the x-axis, but if you are willing to accept the calculator limitations you will have your graph.

Is it possible to graph the locus of Z on the TI 84

Define z=x+iy
Substitute in the equation [x+iy -1-i|=5
|(x-1)+(y-1)i|=5
SQRT ((x-1)^2+(y-1)^2)=5
Raise to the second power (square) (x-1)^2+(y-1)^2=25
This is the equation of a circle of center (1,1) and radius 5

To graph it isolate y as +/- SQRT (25-(x-1)^2)
or use the CONICS application, which you can download from education.ti.com
You can also use the Cabri Jr Geometry application or the Draw menu then the circle(.
