Separable DEs

[alabama14]

Are the following DEs separable?

(y/t)(dy/dt) = t^2*(ln(y^(3t)) + t^3

My answer was no.

(dy/dx) = x/y + sin(x)

Again, my answer was no.

Can you tell me if I am correct?

Are the following DEs separable?

(y/t)(dy/dt) = t^2*(ln(y^(3t)) + t^3 ..... Separable

y/[3ln(y)+1] dy = t⁴ dt

My answer was no.

(dy/dx) = x/y + sin(x)

Again, my answer was no. ... Correct

Can you tell me if I am correct?
