This all seems a bit OTT. It is'nt rocket science.
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
Remembered by the mnemonic SOHCAHTOA
Variations -
sin times hypotenuse = opposite
hypotenuse = opposite/sin
angle = inverse sin [opposite/hypotenuse]
etc etc
Pythagoras hypotenuse ^2 = opposite ^2 + adjacent ^2
Errrr ! Can't think what else you need, unless you never went to primary school. Calculators make it a doddle.
If in doubt, do a Google at the time ? Lots of stuff on the net !
Hope this mainly helps to save you lots of unnecessary work ! The courses themselves, especially condensed ones, stretch endurance to the limit (not least one's limits of sheer boredom) ! Go skiing or something before your course - chill out !
