Sin=O/H Cos=A/H Tan=O/H
Csc=H/O etc

Area Circle = (pi)r^2
Circum Circle = (pi)D

Pascals triangle up to ~ row 9

what can you guys add? keep it on topic plz

Nicely bumped!

I'll add to it.


Surface area of cylinder = circumference x h + (pi)r^2 (2)

[Multiple by 2 for the (pi)r^2 to account for the top and bottom surfaces]
[Excluding the top and bottom surfaces, you would just use circumference x h]

Volume of cylinder = (pi)r^2(h)
[h = height]
