Thanks for this, got confused on this because on Khan Academy, phase shift isn't explained nor is the factoring part.

you could also use addition formula to show this sin(x+90)=sinxcos90+cosxsin90 which equals cosx

Ok, so how do I find a phase shift between two sin graphs?

ah yes my favorite explanation, it is to the right because its the opposite of what you think. its just since to reach any given point x on a curve without a horizontal translation on a curve with a translation, one must position oneself x+c along the x curve, since x+c-c=0. for positive c, this infers a translation to the right.
