In Reply to: Pi is 3.141592... I'm sure you can divide by 2, to get 1/2 Pi. :-)) nt posted by andyr on December 19, 2008 at 23:10:55:
Since no one gets it, I will explain it slowly.Take 2*P1, =, then hit the 1/x key, then hit M+
This stores 0.15915494309189533576888376337251 in the memory.
Hit clear.
Hit MR
Hit /
Enter a cap value in µF.
Hit /
Enter the frequency in Khz.
Hit =
The answer is in Kilohms.
Start out with a reasonable cap value that you can actually buy, you can always get a 1% resistor value you need.
Example:
.159/.1µF/.1Khz=15.9K
By using Kkz and Kilohms and µF, you can use a simple four-funtion calculator and don't need exponential notation (or having to enter a whole bunch of zeros).
