Find the differential of f(x,y)=x3+y2−−−−−−√f(x,y)=x3+y2 at the point (1,2)(1,2).df=
Then use the differential to estimate f(0.94,1.94)f(0.94,1.94).f(0.94,1.94)≈f(0.94,1.94)≈

Motion around a circle of radius a is described by the 2D vector-valued function r(t) = ⟨a cos(t), a sin(t)⟩. Find the derivative r′ (t) and the unit tangent vector T(t), and verify that the tangent vector to r(t) is always perpendicular to r(t).
