s (u, v) 3 h(u, v ) = 1 -3 We have a transformation t(u, v) / with Jacobi matrix at the point f (1,2) = (u (1,2), v (1,2)). What is the Jacobi matrix of the composition hof in point (1,2)? dys. what is the Jacobi matrix of the transformation given by s(u(x, y), v(x, y)) (hof) (x, y) = ? t(u(x, y), v(x, y) ) as as = ay at = at ay
