Trig Finder Calculator Program Problem
04 Sep 2018 08:07:03 pm

Hi,

I have downloaded the TrigFinder 3.0 program for my TI-84 Plus CSE, but it seems to not be working. Whenever I open the program I select degree mode and then I'm prompted to enter a value. I've tried entering different things, for example "90", and then after I hit enter it brings me to the next screen where it shows that I have entered 0 degrees and just gives me the trig values for that. The answers for 0 degrees are the results no matter what value I enter.

Do you guys have any idea what the problem could be? Maybe I'm missing something very simple.

Thanks!

I'm unfamiliar with TrigFinder 3.0, but I think it might be easier just to use the build in trig functions, or write a program of your own. I assume you want a program that shows the sine, cosine, tangent, and their inverses depending on your input in degrees. If you have the calculator on Degrees mode, you can simply type sin(n, cos(n, or tan(n, where n is the angle in degrees.

I've written a little program in TI-BASIC which can easily replace whatever program you're currently using. Simply type in a number and it will give you all the trig numbers that relate to it. Typing a number will assume the number is in degrees. Typing a number and then a Pi symbol immediately following it will make the program assume the number is in radians. Press [ON] to exit the program.

Reply if you have any questions!

This program assumes that you have a more recent version of the operating system where length() and inString() are present.

Code:

While 1


ClrHome


Input "Value:",Str1


Output(2,1,"Sine:


Output(3,1,"Cosine:


Output(4,1,"Tangent:


Output(5,1,"Cosecant:


Output(6,1,"Secant:


Output(7,1,"Cotangent:


If sub(Str1,length(Str1)-1,1)="π


Then


Radian


Output(9,1,sub(Str1,1,length(Str1)-1)+" in Degrees = "+toString(N/(2π)360


Else


Degrees


Output(9,1,Str1+" in Radians = "+toString(N/360π2


End


Output(2,12,sin(N


Output(3,12,cos(N


Output(4,12,tan(N


Output(5,12,csc(N


Output(6,12,sec(N


Output(7,12,cot(N


End
