© = Theta , cause we can't write Theta
P = Perpendicular
B = Base
H = Hypotenuse
Identities:- Reciprocal Identities:-
Sin© = P/H Cosec© = H/P
Cos© = B/H Sec© = H/B
Tan© = P/B Cot© = B/P
Sin©/ Cos© = Tan©
Cos©/ Sin© = Cot©
Three important identities:-
Sin^2© + Cos^2© = 1
Cot^2© +1 = cosec^2©
Tan^2© +1 = Sec^2 ©
Hope it helps.
