Osam Santo found new mathematical formula in Japan. It is next rules. Point=(0,0) Point=(a,d) Point=(c,d) Total angle of circle is not 360. a*d=ad c*d=cd |OA|=|a^2+b^2|^(1/2) |OB|=|c^2+d^2|^(1/2) Angle of ideal triangle(AOB) = 0 ~ (Angle of half circle) 1+1=2 1+3=4 6+7=13 2-1=1 13-6=7 4-1=3 1-1=0 2*2*2=2^3=8 3*3=3^2=9 7*7*7*7=7^4=2401 21/3=7 51/3=17 144/12=12 9/3=3 Next rule is new formula found by Osam Santo. Sin(angle AOB)=|ad-bc|/|OA||OB|

Why didn't European notice it in past time??? One of reason is that European is too high intelligent. So,they would calculate Sin(AOB) from old formula of Cos(AOB). But, ..... cos(AOB)= .........!!! Vector !!!!!!!!!
