Other temperature scales 
 
A temperature scale with 100 degrees between two points is called a centigrade scale (“centigrade” means one hundred 
degrees), and is an obvious scale for use in the metric system where measurements are based on powers of 10. A scale 
with 0 at the freezing point of water and 100 at the boiling point was suggested by Celsius, and is now called the Celsius...

Angular measurements 
 
There are two primary ways of measuring angles, radians and degrees (there is a third way, Grads, which is not used as 
often). Radians measures the span of an angle in terms of the unit circle, where a full revolution involves an angle of 2!. 
Degrees measures the span of an angle where a full revolution involves an angle of 360 degrees....

Variables and Memory Registers 
 
When an equation is typed on the HP 35s, it can use variables with names from A through Z. For example an equation 
 
3X² - 5X= A 
 
has the variables X and A in it. 
 
Variables can also be used in programs and in calculations from the keyboard. 
 
Each variable consists of a number and of a place in...
