Infinity constants on WP-34s Marcel Samek Unregistered Posts: 189 Threads: 39 Joined: Nov 2011 06-19-2013, 06:24 PM The manual (3.1) says that the constants positive and negative infinity are considered numeric values. However, if I try using them as limits to the integrate operator, I get a "not numeric" error. Is this a bug or by design? Paul Dale Unregistered Posts: 3,229 Threads: 42 Joined: Jul 2006 06-19-2013, 09:01 PM By design. The integration code cannot handle infinite limits, so they are disallowed. There are transforms that can be used to reduce the limits to something finite -- old HP manuals detail one procedure. - Pauli Marcel Samek Unregistered Posts: 189 Threads: 39 Joined: Nov 2011 06-19-2013, 09:39 PM Out of curiosity, are there any functions on the WP-34s where the infinity constants can actually be used? Paul Dale Unregistered Posts: 3,229 Threads: 42 Joined: Jul 2006 06-20-2013, 12:13 AM Yes, plenty. Two easy ones: e-infinity gives zero and TANH(infinity) is one. If you are going to start playing with infinities on the 34S, make sure you set the D flag. - Pauli Paul Dale Unregistered Posts: 3,229 Threads: 42 Joined: Jul 2006 06-20-2013, 12:15 AM Also stuff like 1/infinity = zero and 1/-infinity = - zero. - Pauli « Next Oldest | Next Newest »
