I have a number which we'll call α in degrees that represent the angle of a linear function with the X axis. for example when α is 0 the linear function is on the X axis , when α is 360 the linear function is on the X axis. when α is 90 the linear function is on the Y axis. and so on. I want to get from the linear function
y = αx
the X of y = 1, and the Y of x = 1. and I am not sure how can I do that. can anyone post a quick forumla for calc such a thing? does it have a name ? I know trigo may be needed to transfer degrees for a slope that represent the value of y for X = 1.
