Step 1
- The function is \( z = e^x \cos y \). - The relationships are \( x = st \) and \( y = \sqrt{s^2 + t^2} \). Show more…

Use the Chain Rule to find dw/dt. w = xey/z, x = t^3, y = 2 - t, z = 5 + 6t 2. Use the Chain Rule to find ∂z/∂s and ∂z/∂t. z = ercos(θ), r = st, θ = s^6 + t^6

Consider the following. w = x cos yz, x = s^2, y = t^2, z = s - 4t (a) Find ∂w/∂s and ∂w/∂t by using the appropriate Chain Rule. ∂w/∂s = 4s cos(t^2 s - 4t^3) - s^2 t^2 sin(st^2 - 4t^3) ∂w/∂t = --4s^3 t sin(st^2 - 4t^3) + 12s^2 t^2 sin(st^2 - 4t^3) (b) Find ∂w/∂s and ∂w/∂t by converting w to a function of s and t before differentiating. ∂w/∂s = 4s cos(st^2 - 4t^3) - s^2 t^2 sin(st^2 - 4t^3) ∂w/∂t = 4s cos(st^2 - 4t^3) - s^2 t^2 sin(st^2 - 4t^3)
