KMUNIVERSE mathtricks Trignometry ratios TRIGNOMETRY Trigonometry the branch of mathematics concerned with specific functions of angles and their application to calculations Now as per sine cosine and tangent formulas we have here: Sine θ Opposite sideHypotenuse BCAC Cos θ Adjacent sideHypotenuse ABAC Tan θ Opposite sideAdjacent side BCAB We can see clearly from the above formulas that: Tan θ sin θcos θ Now the formulas for other trigonometry ratios are: Cot θ 1tan θ Adjacent side Side opposite ABBC Sec θ 1Cos θ Hypotenuse Adjacent side AC AB Cosec θ 1Sin θ Hypotenuse Side opposite AC BC The other side of representation of trigonometric values formulas are: Tan θ sin θcos θ Cot θ cos θsin θ Sin θ tan θsec θ Cos θ sin θtan θ Sec θ tan θsin θ Cosec θ sec θtan θ Sin Values sin 0 0 0 sin 30 14 ½ sin 45 12 12 sin 60 34 32 sin 90 1 1 Cos Values cos 0 1 cos 30 32 cos 45 12 cos 60 12 cos 90 0 Tan Values tan 0 01 0 tan 30 1434 13 tan 45 1212 1 tan 60 32½ 3 tan 90 10 for cosec sec and tan you just reciprocal the sin cos tan value respectively.
