10. ### show that the vector-valued function r(t) = e^-t costi + e^-t sintj + e^-tk lies on the cone z^2 = x^2 + y^2?

r(t) = e^-t costi + e^-t sintj + e^-tk This shows that point (x, y, z) is parametrically (e^-t cost, e^-t sint, e^-t) LHS= z^2= e^2t RHS= x^2 + y^2= e^2t( cos^2t + sin^2t )= e^2t So vector lies on cone
