What's New

New Taculator commands available!
+ 2-PropZ-Interval
+ Chi²-Test
+ Chi²GOF-Test
+ LinRegT-Test
+ LinRegT-Interval

We fixed some bugs and improved a lot of functions:
+ Tracing functions is now more accurate.
+ While tracing you can enter an x-value and Taculator will show the y-value. Press the TRACE button and enter any value.
+ A black graphing screen due to a wrong window setting of too small values for Xscl and Yscl has been fixed.
+ Use the nDeriv and fnInt commands in the Y= menu to graph the derivative or integral function.
+ You can now graph families of functions by using the following syntax: {1,2,3}X.
+ Many more bugs have been fixed.
