Hello there!
I can assume you mean "Pi".
Pi is an irrational number that has an infinity decimal, also known as a terminating decimal, which means to repeat infinitely.
The summarized form of Pi is 3.14, but since you have multiple units, I can assume you want the extended form.
Here it is:
3.14159265359
I hope this helps!
This is in the 3rd quadrant, so -12 is the adjacent side of the 5,12,13 triangle.
Cot(theta) = -12/(-13) = 12/13
Formula: y=mx+b
(4,-1)
4 is x
-1 is y
m=1/2
-1=1/2(4)+b
1/2(4)=2
-1=2+b
-1-2=-3
-3=b
y=1/2x-3
That's division. It show up as a slash in calculators and computers.
