why is 1/AD = cos(α - π/2)?
fuck I forgot to put in the letters, lemme fix
somebody help a poor soul
Do you know basic trig?

I'm learning it

So you know SOHCAHTOA? Hypotenuse*cos(theta)=adjacent length
alpha is the entire angle but you only need the angle from the triangle so you subtract pi/2 or 90 degrees

thanks, I'm just caffeinated and underslept, you stating that made me feel dumb when I realised what it was :(
