Which language are you using? |
Re: Scientific Calculator Help! by ektbear: 7:51am On Aug 09, 2012 |
log should be in most programming languages. sinh, cosh, tanh, you can implement yourself from the formulas, assuming you have the exponential function. See this: http://en.wikipedia.org/wiki/Hyperbolic_cosine |

@naija_swags,@@mj and @ekt_bear, I'm using VB. I have tried to use the exponential formula i mean ((ex+e-x)/2) yes it didn't work. I guess there should be a conversion before inserting the variable x. In the issue of the sin,cos and tan,i converted any degree to radian before plugging it in the equation. Pls,i need more hint. |

Phemmmy: @naija_swags,@@mj and @ekt_bear, In what sense did it not work? You wrote a function like this: def sinh(x) return (exp(x)- exp(-x))/2 and it failed? How? |
