Properties = Facts

 properties of equality 8 balance fact 4 transitive property 6 swap fact 2 substitution property 7 swap fact* 2 addition property 6 add fact 2 multiplication property 8 times fact 2 distributive property 7 spreading fact 3 reflexive property (A=A) 6 is fact 2 symmetric property (if A=B, then B=A) 6 turn-same fact 3 symmetric property (if A=B, then B=A) 6 turn-same fact 3 the inverse (p>q, not p>not q) 3 the not 2 the converse (p>q, q>p) 3 the flip 3 conditional statement 6 if-say 2 complement 3 fill 1

* transitive and substitution are not both needed

Trigonometry = Three-Nik Zooming

 trigonometric tables 7 3-nik tables 4 trigonometric ratios 7 three-nik "to"s 3 adjacent 3 by 1 opposite 3 far 1 hypotenuse 4 long 1

sine ratio = far/long or FoL [far side over long side]
cosine ratio = by/long or BoL [by side over long side]
tangent ratio = far/by or FoB [far side over by side]
cosecant ratio = long/far or LoF [long side over far side]
secant ratio (4) = long/by or LoB [long side over by side]
cotangent ratio (5) = by/far or BoF [by side over far side]
[sin/cos = tan, this is immediately evident when you write FoL/BoL = FoB]

Thus:

sin = fol (far over long) or f:l or f/l or F/L or F:L

 sin 1 fol (far over long) 1 cos 2 bol 1 tan 2 fob 1 csc 3 lof 1 sec 2 lob 1 cot 3 bof 1

The relationships of the various triangle ratios (trigonometric ratios) are immediately evident. With fol used for sin there would be no more looking up sin to see that it is the opposite over the hypotenuse. It is immediately apparent that it is the far side over the long side of a right 3-nik (triangle).
Also, fob = fol/bol, and fol 30 = 0.5, bol 30 = 0.866, and fob 30 = 0.577.

Calculus = Curve Science or Curves
