Question

What is the formula for finding a trigonometry ​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

Basic Formulas

By using a right-angled triangle as a reference, the trigonometric functions or identities are derived:

• sin θ = Opposite Side/Hypotenuse.
• cos θ = Adjacent Side/Hypotenuse.
• tan θ = Opposite Side/Adjacent Side.

Answer 2

${\underline{\pink{Basic\ Formulas\ :-}}}$

By using a right-angled triangle as a reference, the $\bold{<em><u> </u></em>trigonometric }$ functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.
