Don't give up on writing mathemamatics on the Web! With Mathyma you can now easily write all sorts of mathematical expression directly into your Web page:
|
~ax^2 + b~x + c = 0 _ _ _ _ => _ _ _ _ ~x _ = _ fract{-~b +- &sqrt.${ ~b&powtwo. - 4~a~c },2~a} |
What about some matrix algebra?
|
matrix{ 1 , 6 / -2 , 2} matrix{ 6 / 9 } _ _ = _ _ matrix{ 60 / 6} |
and integration becomes a doddle:
|
int{ fract{ - 1 , &sqrt.${~a&powtwo. - ~x&powtwo.}},,, d~x } _ = _ cos^{-1} rndb{fract{~x,~a}} |
