Homework Statement: At what average rate does the magnetic field need to change to induce emf of 1.0 V.
See attachment question 1.

Relevant Equations: See attachment solution.

Why does Δ(BA) = AΔ(B) when A is constant?
Is there a proof for this algebra?
Thanks

Δ(AB) = (A+ΔA)(B+ΔB)-AB = AΔB+BΔA+ΔAΔB.
If A constant then ΔA=0, leaving only AΔB.
