The problem is, if a beacon to three year old Mick to want find a doctor, be such that this kind of a projection of feet onto a is they got you too. So a lot b is equal to you. Want me to three? Then as definition of the scalp projection of be onto a, we have they not be over magnitude off a stick or two. Toby Half three B one minus B three over. You're a tough ten. Is their country too. So three B one minor speed three is equal to two hams. Which of ten we can choose the one you called zero the three Continetti ve two hams root of ten on B two. Coming. I remember. See, we can't. Might be too weak or too. Why? Back to you. Zero one Negative two time spirit of ten. Thank you. If b if we go to this work too, then the scanner projection ofthe beyond Toei is they got to
