Having trouble creating functions for scientific calculator

[qqchrono]

Hello!

I got tasked recently to create a calculator which i have managed to create a standard one with a few basic functions... The problem comes when i tried to escalate it into a scientific calculator which is actually just adding tan,cos,sin,tan-1,cos-1,sin-1 functions (I know that's not all to a scientific calculator haha but this'll suffice). Been stuck at these functions for awhile now.
Coming from a weak maths background i tried prowling the internet for information on the formulas but could not find one with a formula that could explain it in a way i understand. Could anyone offer any input or help on this?

Thanks!

As tan, sine, cosine and so forth are built into LiveCode
people like You and I can "cheat", and not get all worried about the shame
of being bad at Maths at school.

It doesn't even have to be the stock dictionary, you can make any of these your new best buddy !

*Brian's page is actually the stock dictionary, just much much _-`faster.

Here is one (by MaxV). Has more features than you need.

Hi.

As Richmond said, all the functions you mentioned are native to LC. So my question to you is this: Did you just not know that, or are you having difficulty implementing them?

In other words, and never mind how the user interface might work, are you able to simply:

Code: Select all

on mouseup
ask "Enter angle"
if it is a number then answer sin(it)
end mouseUp

And do you know that the arguments to trig functions are in radians?

That's stated explicitly in the dictionary.

Yes, I know. And I even know what radians are

Ah.

Oh thats weird the first time i checked i only found atan, asin, acos which i have no idea what they meant. I tried looking it up in the dictionary before because i used sqrt for the calculator.

Thanks for pointing that out, will look through again.

Yes i would be able to code it. My mistake i missed the function out completely
