RE: New guy and programming problem
I never knew trig function were used as logarithm !
Example: arccos/cos vs ln/exp 0.123 * 0.456 = cos(82.9347°) * cos(62.8707°) = 1/2 (cos(82.9347° + 62.8707°) + cos(82.9347°  62.8707°)) = 1/2 (cos(145.8054°) + cos(20.0640°)) = 0.05608822 ~ 0.056088 0.123 * 0.456 = exp(ln(0.123) + ln(0.456)) = exp(2.09557 + 0.78526) = exp(2.88083) = 0.05608819 ~ 0.056088 But, how can trig function used for division ?
