cos(phi - 1) = cos(phi)cos(1) + sin(phi)sin(1)
How is the golden ratio worked out?
(a+b)/a=a/b=phi (the golden ratio, as defined) (a+b)/a=phi (we'll solve this equation) 1+b/a=phi (just changing the form of the left side a little) 1+1/phi=phi (a/b=phi so b/a=1/phi) phi+1=phi2 (multiply both sides by phi) phi2-phi-1=0 (rearrange) From here, we can use the quadratic equation to find the positive solution: phi=(-b+√(b2-4ac))/(2a) phi=(1+√(1+4))/2 phi=(1+√5)/2≈1.618
What happens if your phi value for an effect size is negative?
I don't know but i need to know internet my assignment is due tomorrow i cant find it anywhere on the ahh math
