I am working on a code that requires me to embed trignometry formula. actually i have the formula but i am confused how to implement that into my code.i am trying to find out everywhere & i am getting too but not getting exactly what i need.the formula is like

Axh = Ax cos θz 
Ayh = Ay cos θy

|AI | =sqrt(|Axh|^2 + |Ayh|^2)

α = arccos(Axh/|AI|) β = arccos(Ayh/|AI |)

Alat =Axh sin α+ Ayh sin β

these are formulas so anyone out there can help me with geometric coding or any simple project from where i can learn.. thanks

Have a look at this article where I had a bunch of formula, and had to translate to code, ok, its not objective-c, but might give you ideas on the task.

Remember, keep it simple and break each part down to its component parts.

Solution 2

AFAIK Objective C has the same mathematical functions of the C programming language, hence you have all you need (have a look at math.h header).
For instance first line would be

C

double Axh = Ax * cos(Thetaz)

and so on.
