Question about Texas Instruments TI-83+ Graphing Calculator (TEX83PL)

# TI 83 I am in a math class that we have to use the calculator to get our answer. Well my qeustion is can I use the TI 83 to calculate compound intereset or do I have to use the ti-83 plus to calculate the compound intereset. If I can use the TI 83 when I go about calculating the compound interest. Thank you Veronica Contreras

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
(I know this because I have a TI-83 calculator)

No, you should be able to use the TI-83 calculator to solve compound interest. It's just a matter of knowing the formula. The equation should be entered like this:

P x (1 + (R / N)) ^ (N x T)

Where:
P = Principle
R = Rate of Interest
N = Number of times compounded per YEAR
T = Number of years to compound

You will get the amount that the principle is worth at the end of T years plus the interest accrued.

Note: Type the equation in (with the numerical equivalents of course, not the letters) EXACTLY as I have it up there (but without the spaces)!!!

### Arctan function is not computing correct answers. for ex. artangent or tan-1(1) = .785 not 45 degrees

Perhaps you need to go to "Mode" and switch "Radian" to "Degree" or vice versa.
I'm not entirely sure because I don't follow any more math/science classes, but I remember there sometimes being a problem with those specific settings.

### I am in a math class and i have a TI-83 plus calculator and we are doing stuff with polynomials. how do i type in to it something like (5x)(6x) and get the answer 30xsquard

ahh well maybe i not familiar enough but i think you need programs 2 do that, you get a usb cord wire and look up for free program from ti site they should have it there and then you can download some program and run it.

to clarify your problems type ti-83+ on google and see the texas instrument site where they should have program and cord for sale.
