Hello there, 

Would you please tell me how to get the 'Desired' expression from the 'Sec_Z2prim' expression?

My 'Attempt' did not work.

TR_turns_ratio := N = n2 / n1;

N = n2/n1

Sec_Z2prim := Z1 = Z2*n1^2/n2^2;

Z1 = Z2*n1^2/n2^2

Attempt := subs(TR_turns_ratio, Sec_Z2prim) assuming (n1 > 0, n2 > 0);

Z1 = Z2*n1^2/n2^2

Desired := Z1 = Z2*(1/N)^2;

Z1 = Z2/N^2

Thank you,
