Trigonometry Rules

We can all use log tables to look up these rules, but I am going to show you one method that will hopefully speed up your trigonometry.
Sin, Opposite, Hypotenuse, Tan, Adjacent, Cos.

There are several methods to remember this, when I was in school my maths teacher said it like this:
So, tow a car!
SOH (So) TOA (Tow A) CAH (Car)

My favourite one and it always sticks in my head is this one:
Some Old Hag Carries A Heavy Tin Of Apples

So now you can fiques it out easily

SOH = Sin of Opposite over Hypotenuse

CAH = Cosine of Adjacent over Hypotenuse

TOA = Tan of Opposite over Adjacent

Another Way:

S illy Old Harry Had A H andful Of Apples

 

Two Old Angels
Sitting On High
Chatting About Heaven

 

Oh hell another hour of algebra
Oh hell——–opposite ovr hypoteneuse
Another hour——–Adjacent ovr hypoteneuse
Of algebra———opposite ovr adjacent
