Sharp EL-W506T vs. Sharp EL-W516T

[lrdheat]

The TI 30X Pro MathPrint is much faster than the 36X Pro, rather identical to the 991EX in speed and integration answers...I’m guessing that the TI is using the same integration method as the CASIO. Both the CASIO and TI correctly throw errors with the integral that you asked about. The 30X can accept much longer equations than the 36X Pro. I did not have the patience to test how lengthy an expression is possible, but much better than the frustratingly small capacity of the 36X Pro. I really like the 30X. I like how it uses a default epsilon of 1E-5 in it’s integration and differentiation operations, but in the math menu, allows the user to choose a much finer epsilon if desired...I can key in 1E-9, for example, or anything else that I might desire.
