∂(v(t),t) [enter] returns diff(v(t),t,1)

∫(Ans,t) [enter] returns ∫(diff(v(t),t,1),t) The expected result is v(t)

∫(∂(v(t),t),t) [enter] returns ∫(diff(v(t),t,1),t) The expected result is v(t)

now

∫(diff(v(t),t),t) [enter] returns v(t)

∫(Ans,t) [enter] returns ∫(diff(v(t),t,1),t) The expected result is v(t)

∫(∂(v(t),t),t) [enter] returns ∫(diff(v(t),t,1),t) The expected result is v(t)

now
