Hey, can anybody help me with this error equation and change of variables question?
I've tried entering
X = (Io*Cos^2(b))/Y
X = (Io*Cos^2(b))/Z^2
And apparently neither are correct for "X =" and I'm at a loss for what to try next.
I actually ended up figuring out the first three answers. The question seems to be very poorly worded.
X = Io
Y = Z^2
Z = cos(b)
Change of variable almost always means substitution outside of calculus so for me and several other the obvious thing was to sub I = XY into I = Io * Cos^2(b). What it seems they meant was if X=A*B and X =C*D then A = C and B = D.
Now I'm stuck deciphering the rest of it.
Looks like it.
I was just reading over this
I was confused by the symbol they were using buy I guess that's just another symbol for delta.
