-------------Description:
This program is a collection of Calculus applications. They are: Arc Length, Centers of Mass, Delta and Epsilon v1.00, Delta and Epsilon v2.00, Euler's Method, Function Explorer, Growth and Decay, Implicit Differentiation, Initial Value Derivatives, Integrals, Limits, Linearization, Max/Min Finder, Mean Value Theorem, Mode Changer, Mode Saver/Loader, Newton's Method, Normal Line, Simpson's Rule, Surface Areas of Revolution, Tangent Line, Taylor Polynomial Approximation, Trapezoidal Rule, and Volumes of Revolution (note that Mode Changer and Mode Saver/Loader are not related to Calculus). 



-------------Instructions:
Transfer the CALC1LGM.89G group file to your calculator. To run the program, you need to type "calc1lgm\calcpack()" on the home screen (the fifth character in the directory name "calc1lgm" is "1" - "one," not "L" or "l"). The program automatically changes the current folder to CALC1LGM and changes mode settings to those required by most programs. You do NOT need to change your mode settings back -- the program automatically saves the original mode settings and restores them when you exit the program. 
After you run the calcpack program, you need to choose an application by using F1-F6 keys (a fast way to exit is to press 2nd+F1). Then just press enter and the program will be executed. After that program has finsihed its job, you are brought back to the main CalcPack menu. 
There is an on-calc help file. You can open it through the TOOLS menu-->INSTRUCTIONS. This file is about 4.8 kB -- if you want to delete the file, choose the DELETE INSTRUCT. option from the TOOLS menu. That way you will free up about 5 Kb of memory. 



-------------Update(s):
Added Growth and Decay, Initial Value Derivatives, Taylor Polynomials, and Euler's Method. Updated instructions. 



-------------Known Bugs and Important Notes:
None (in case of difficulty, pay attention to reported errors, e.g. there may not be "=" if you are asked for "f(x)")
