Unfortunately the Amazon link is for 12V, not 22.2V, and I don't know enough to follow the circuit schemata you've got there. I found this DC-DC regulator on batteryspace, which I might be forced to buy given my time constraints and the current state of my project. This has a max throughput of...
Thanks for the welcome!
I'm using this Acer R240HY bidx monitor. I'll try their support now. There doesn't seem to be specifications for input power on the Internet, but the power brick and sticker on the monitor state 19V at 1.3A DC power.
Perhaps I should've been more specific in my original...
I've got two monitors I am trying to power with a battery. They accept 19V @ 1.3A each, and I'll have them in parallel off a single battery, so they'll need 19V @ 2.3A from the battery. I'm looking at http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=56845. The specifications...
Thank you so much! I finally got to the discriminant point some time after posting this, but I tossed it aside because I forgot that b was 2b not just b, so I got b^2 > 96c. Thanks for the help!
Hello, been thinking on this one for a little while, and can't seem to figure it out. Problem statement is:
The cubic curve y = 8x^3 + bx^2 + cx + d has two distinct points P and Q, where the gradient is zero.
Show that b^2 > 24c.
It seems simple enough, but I can't logic it out. This...
