How to convert from polar to complex

How can I convert such as 5 at an angle of 120 to a complex number ( a+-bi)

Answer 1

[madhan ravi]

5*exp(deg2rad(120)*i)  %which is in eulers form r*e^(theta*i)

5 - radius

120 degrees converted to radians

see https://en.wikipedia.org/wiki/Euler%27s_formula

I had done the traditional way of converting. the same way of yours a= 5*exp(i*120*pi/180); your code is more professional because you used the in-built function deg2rad.. thanks
