User:TheGunner123/Cos = Ad/Hyp

The Cos = Ad/Hyp upgrades from the Sin = o/h at level 90. It looks like a cos wave.

Weapons
It has a calculator for its weapon. It also has a right-angled triangle.

Attack types
The calculator will shoot out large sums which do the same damage as the answer to the sum. Also, the triangle can spawn loads of ai triangles.

Trivia
I read a book about trigonomogeometry which inspired me to make the Sin = o/h branch.

Further upgrades to the Tan = O/A.
