1. Initially, Learn the Basics

Initially, it is imperative to gain proficiency with the fundamentals. Geometry works for right calculated triangle. The right calculated triangle comprises of three regions – Perpendicular (P), Hypotenuse (H) and Base (B). Essentials assists you with recalling the proportions, yet additionally helps a ton in tackling geometry issues, particularly identified with tallness and distance issue.

Sin (Theta) = P/H, Cos (Theta), B/H, Tan (Theta) = P/B

P – Perpendicular, B – Base and H – Hypotenuse

The right calculated triangle ABC is correct calculated at B, with point 'Ɵ' at C.

2. Recollect the Hindi Mnemonic

Sin (Theta) = Perpendicular/Hypotenuse, Cos (Theta) = Base/Hypotenuse and Tan (Theta) = Perpendicular/Base. Presently, the fact is how you would recollect this? That is the point at which the part of Hindi mental helper assumes a significant part. Pandit Badri Prasad, Har Bole.

Sin (Theta) Cos (Theta) Tan (Theta)

Pandit (P)/Badri (B)/Prasad (P)/

Har (H) Har (H) Bole (B)

3. Opposite of Sin, Cos, and Theta is Sec, Cosec and Cot separately

When you recollect the proportion of transgression, cos and tan, then, at that point you can without much of a stretch recall sec, cosec and tan. Sec, cosec and tan are the converse of transgression, cos and theta separately.

Sec = 1/cos which is proportional of cos

Cosec = 1/sin which is equal of transgression

Bunk = 1/tan which is proportional of tan
