based on right-angled triangle their 6 ratios in Trigonometry, this are basically called Trigonometric functions .The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent.The value of each function can be find out using below trigonometric formulas
Here are the definition of each of this trigonometric formulas
trigonometric formulas
sin θ = opposite Side/hypotenuse where θ is the angle cos θ = adjacent Side/hypotenuse where θ is the angle tan θ = opposite Side/adjacent Side where θ is the angle sec θ = hypotenuse/adjacent Side where θ is the angle cosec θ = hypotenuse/opposite Side where θ is the angle cot θ = adjacent Side/opposite Side where θ is the angle
As per the above table definition we can relate each of the formula in below ways
cosec θ = 1/sin θ hint : 1/opposite Side/hypotenuse = hypotenuse/opposite sec θ = 1/cos θ hint : 1/adjacent Side/hypotenuse = hypotenuse/adjacent Side cot θ = 1/tan θ hint : 1/opposite Side/adjacent = adjacent Side/opposite Side sin θ = 1/cosec θ hint : 1/hypotenuse/opposite Side = opposite Side/hypotenuse cos θ = 1/sec θ hint : 1/hypotenuse/adjacent Side =adjacent Side/hypotenuse tan θ = 1/cot θ hint : 1/adjacent Side/opposite Side = opposite Side/adjacent Side
we can find each of the six trigonometric functions values using above trigonometric formulas
