Answer 1

Trick to learn the formula :-

Papa Beer Peelu

Ha     Ha     Beta

                                Therefore, Sin∅ = P/H , Cos∅ = B/H , Tan∅ = P/B

                                             Cosec∅ = H/B , Sec∅ = H/B , Cot∅ = B/P

                                       (where, P = Perependicular distance

                                                                               B = Base distance

                                                        H = Hypotenuse distance)

→Sin²∅ + Cos²∅ = 1

→ 1 + Tan²∅ = Sec²∅

→ 1 + Cot²∅ = Cosec²∅

Answer 2

Answer:

Solution :

Pakistan Bhukha Pyasa

Hindustan Hara Bhara

P/H, B/H, P/B

=> P/H = Sin theta,

B/H = Cos theta

P/B = Tan theta.
