I've been trying to make a scientific calculator and i couldn't continue because of some special functions such as
LOG
SINH
COSH
AND TANH
Please,if you have any help on this,i'll be waiting for your response.

Which language are you using?

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

I've worked on dz before, I use Java in doing it, what programming language are you using for it? My system was stolen so I dnt have the code again, I could have jst sent it to you. Takia.

Check java.lang.math class if you are using java!

@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.

Thanks for sharing.

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?
