Understanding exponential equations can be a difficult task but this program simplifies understanding. Both from an educational standpoint where the student needs to understand coefficients and intercepts or from an engineering standpoint where the user needs to understand the relationship of thermal heating. this program solves equations in a user friendly environment. Both a help screen and glossary of terms have been included to simplify understanding. The equation of the curve takes the form of Y = a * Ln(x) + b for natural log or base “e” and Y = a * log10(x) for base 10. I have added the reverse log or Y = a* e^x + b for base “e” and Y = a * 10^x + b for base 10. Coefficient variables a and b have been added to make the program more flexible but initially they can be set to a = 1 and b = 1 for simplicity. A “Solve For:” button allows the problem to be setup in either form as described above. Using the adjustor controls or retro keyboard the equation is displayed automatically. A graph shows the actual curve and the user can manually change the scale to achieve the desired view. Additionally a log scale option has been added to allow large excursions of data in x to be viewed more easily. This is all very confusing at first but this program helps to simplify understanding by using adjuster inputs to see how changing the values affect the result. a graph of the actual curve or line is displayed as the variables are changed. Help and glossary screens are also provided to further help in understanding logarithmic equations. When you are done simply Email the results to your home computer for further analysis. This program is a must for Students and Engineers. It makes the complex understandable. Simply the best exponential equation program.
