What is the trigonometry basic formula?
In trigonometry, there are six fundamental trigonometric ratios. Trigonometric functions are another name for these ratios. Sine, cosine, secant, cosecant, tangent, and cotangent are the six essential trigonometric functions. The right-angled triangle is used to generate trigonometric functions and identities. We may use trigonometric formulas to get the sine, cosine, tangent, secant, cosecant, and cotangent values when we know the height and base side of the right triangle.
1. sinθ=OppositeSide/Hypotenuse
2. cosθ=AdjacentSide/Hypotenuse
3. tanθ=OppositeSide/AdjacentSide
4. secθ=Hypotenuse/AdjacentSide
5. cosec θ=Hypotenuse/OppositeSide
6. cotθ=AdjacentSide/OppositeSide
