Hey !!
Cos∅ is defined as Base(side adjacent to angle ∅) /Hypotenuse
Cos∅ = B/H
Some important formulas related to Cos∅ are
Cos∅ = 1/Sec∅
Cos²∅ = 1-Sin²∅
Cos2∅ = 1-Tan²/1+Tan²∅
= Cos²∅-Sin²∅
= 1-2Sin²∅
= 2Cos²∅-1

hey there!
cos Q = base / hypotenuse
==============================
SOME IMPORTANT RELATIONS OF COS ARE -
1) cosQ = 1/secQ
2) cos^2Q = 1- sin^2 Q
3) cos2Q = 1 - 2sin^Q
4) cos2Q = cos^2 Q - 1
