Description
This application is a slide rule simulator. The slide rule (a.k.a. slipstick) is an mechanical analog computer which was formerly used for various scientific calculations, engineering design and surveying. It consists of three linear strips and a sliding cursor and is used for multiplication, division, square, cube, square root, cubic root, trigonometry, logarithm and so on. Please note that trigonometry and logarithm are not supported and the width of the scale is 900 pixels in this version.

Feature Request
Would like the slide rule to remember its position (calculation) when leaving and returning to it.
Would like to be able to rotate to all four orientations.
Would like support for full ipad resolution.
Please continue compatibility with iOs 3.1.x
If I put a value of 4 on B scale under 2 on A scale and look at B scale under 5 on A scale, it does not quite line up to the expected value of 10.
Looking forward to these modifications to upgrade my rating to 5 stars.
Thank you.
Works great! (needs trig and log scales)
I'm a 20-something engineer, and each year during Engineering Week, my workplace holds a slide rule competition to see who in the office can solve math problems using a slide rule. I like learning useless skills, so I decided to learn how to use a slide rule so I could compete. I found this app last year and it was awesome! It's also a good way to introduce the younger generation to this out-of-date math tool.
The only problem I have with this app is that it doesn't include a trig scales or the log scale. Not only would adding those scales improve the quality of the app, but it will also allow me to use the app in the competition (because it always includes trig and log problems).
