Question

Trigonometric formulas

Answer 1

© = 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.
