Right!
No more errors.
Much faster.
Even transforming functions with dephase.
Look at these times...
Function: 1 + t + 2*t^2 + 3*t^3 + 4*t^4 + 5*t^5 + 6*t^6
HP: 8.9 sec
TI: 10.6 sec
Rate: 0.84 (HP wins!)
Both gived identical answer display than MapleV.
Function: 1 + t*sin(t) + 2*t^2*sin(2*t) + 3*t^3*sin(3*t)
HP: 10.5 sec !!!
TI: 137.3 sec
Rate: 0.077 (HP wins!)
Both gived different answer display than MapleV.
Function: exp(5*t-3)+4*t^2*sin(7*t-Pi/3)+2*t^3/5
HP: 74.6 sec
TI: 79.1 sec
Rate: 0.94 (HP wins!)
Both gived different answer display than MapleV.
