7+ y The equation of the tangent plane to the graph of f(x, y) at the point (1, 3, 5) is Z Answer entry help: Note z = is already written, if you write it again the system will read z = > =. . . and treat it as a mistake. I will NOT add points for such a mistake. Write x^y for ry Write x*y for x . y (* is required) Write cos(theta) for cos @ (parenthesis are required) Write sqrt(z) for Vz (parenthesis are required) Write cos(sqrt(z)) for cos( vz) Write cos(sqrt(z))*sqrt(\\pi/2) for cos(vz) 7/2 Write pi for IT Write e for eLet 2 = Ax + By + D be the tangent plane to the surface given by Inc Z = y at the point (1/8, 1, - In 8). Then A B D Answer entry help: Write u^v for u" Write u*v for u . v (* is required) Write e for e Write In(u) for In u (parenthesis are required)Compute the derivative of ag 3;) = $23; + :r: with respect to t where: t} = 6:54 and y(t} = e3 vour answer should have only the variable t in it. 013' W A : = nswer (It Write vr'u for U\" Write v*u fer tr - u If\" is required} Write v*{u+w} for life: + w} {parenthesis and * are required} Write e fer e (parenthesis are required} Compute the partial derivative of f(x, y) = a + ey with respect to r where: x(r, s) = & cos(3r) and y(r, s) = 68 +r Your answer should have only the variables r and s in it. of Answer: = ar Answer entry help: Be careful with brackets, check how the system interprets your answer. Write v^u for yu Write v*u for v . u (* is required) Write v*(u+w) for v(u + w) (parenthesis and * are required) Write e^ (utv) for e (parenthesis are required) Write cos(theta) for cos 0 (parenthesis are required)
