Sohcahtoa is an abbreviation (SOH) sine opposite hypotenuse (CAH) cosine adjacent hypotenuse (TOA) tangent opposite adjacent.

It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle

when is the estimation of product is a useful tool

dimensional anaylisis is useful for many reasons, mainly because without it YOU AINT SHIzznitt so there for it is very useful

"SOHCAHTOA" is a helpful mnemonic for remembering the definitions of the trigonometric functionssine,cosine, andtangent.Sine = Opposite over HypotenuseCosine = Adjacent over HypotenuseTangent = Opposite over AdjacentOther mnemonics include:1. "Tommy On A Ship Of His Caught A Herring" (probably more common in Great Britain than the United States).2. "Oscar Has A Hold On Angie."3. "Oscar Had A Heap of Apples."4. "The Old Army Colonel And His Son Often Hiccup" (which gives the functions in the order tangent, cosine, sine).5. "Studying Our Homework Can Always Help To Obtain Achievement."6. "Some Old Hippy Caught Another Hippy Tripping On Acid."
