Здравствуйте, Козловский Константин Викторович!
x'(t)=2t/(1+t^2)
y'(t)=1-(1/(1+t^2)) = (1+t^2-1)/(1+t^2)=t^2/(1+t^2)
y'/x' = t^2(1+t^2)/(2t(1+t^2)) = t/2
x'(t)=2t/(1+t^2)
y'(t)=1-(1/(1+t^2)) = (1+t^2-1)/(1+t^2)=t^2/(1+t^2)
y'/x' = t^2(1+t^2)/(2t(1+t^2)) = t/2

Здравствуйте, Козловский Константин Викторович!
y'x=y't/x't=(1-1/(1+t2):2t/(1+t2)=(1+t2-1)/2t=t/2=[$8730$](ex-1)/2
y'x=y't/x't=(1-1/(1+t2):2t/(1+t2)=(1+t2-1)/2t=t/2=[$8730$](ex-1)/2
