Hi all, I am new to SMath because I'm looking for a nice elegant solution for some standard formulas and problems that I do for my work relating to electrical engineering.

I love the idea of the nice and elegant solution to presenting these maths equations, and ability to work with complex numbers. In electricity, it is always in polar form. I seem to be able to add, subtract, multiply and divide complex numbers after entering them in polar notation, i.e. magnitude with degrees. However, I cannot display the angle of a complex number. I'd like to be able to write Answer = Mag < Angle(deg). But I can only get Answer = Mag. Is this possible to do, without having to use other trigonometry inbetween? In which case, I may as well stick with Excel.

Thankyou in advance.

Try; arg()

Angle_radians=arg(1+1*i)=0.7854

Angle_degrees:180/π*arg(1+1*i)=45

Thankyou, but, sorry... I must be doing something wrong here?



I can't understand why I'm getting zero values, perhaps I'm entering the angles incorrectly?

Indeed, you do.

You are adding radians to degrees not real and imaginary components.
you would need to make a function to convert polar representation to cartesian representation and back.

Thanks Lupus. I think in which case I'll use Octave instead. It's not quite as elegant looking as SMath and neat for copying into reports, but simpler for entering complex numbers in polar form, etc.
