Question

any tricks for trigonometry?

Answer 1

Hii There!!!

In point of view, there is no tricks for trigonometry. But you must learn all the formulae given in the chapter and one more thing try to convert the equation firstly into sin and cos that will be much easier to solve R.H.S and L.H.S equating questions. You may also understand about methods given in questions. I think to be perfect in trigonometry you must try to practice more and more questions.

Some basic formulae are :-

1) sin θ = p / h

2) cos θ = b / h

3) tan θ = p / b

Where,
h= height , p= perpendicular and b= base


Some more identities :-

◆sin^2 θ + cos^2 θ = 1

◆ 1 + cot^2 θ = cosec^2 θ

◆ 1 + tan^2 θ = sec^2 θ

Answer 2

There is a trick to learn formula
One is for learning their formula of sin cos tan cot sec cosec

_PBP_______
HHB

WHERE ❄P= PERPENDICULAR
❄B=BASE
❄H=HYPOTENUSE

✌SIN = P/H
✌COS =B/H
✌TAN =P/B
