Hey there! I started studying RStudio a while ago and today I went through a question. Considering the Cartesian place, I want to generate a random angle (deg or rad not important) with only the x-axis and I want to consider only the 180 degree angle of the two upper quadrants. I post a photo to make it clear.
Thx in advice for the replys.
Just draw one number from the uniform distribution on the interval [0,180] ?

Thx for the reply! Yeah I have already done this but I have to be sure that the interval is in the upper part of the plane, because if I want to draw the tangent of that angle I want a positive angular coefficient from 0 to 90 degree for example.
I studied mathematics in the Netherlands in Dutch so I may miss something here: how do you 'draw the tangent of an angle'? If you want the tangent to be positive then just restrict to the first quadrant (??)
I’m sorry I was meaning to calculate the tangent. How can I restrict ?
set.seed(2021) runif(1,min=0,max=90)
