3. ### Change from rectangular to cylindrical coordinates. (Let r ≥ 0 and 0 ≤ θ ≤ 2π.)?

x = r cosθ y = r sinθ z = z x² + y² = r² y/x = tanθ (x, y, z) = (5, −5, 3) r² = x² + y² = 25 + 25 = 50 ----> r = 5√2 tanθ = y/x = −5/5 = −1 (θ in QIV) ----> θ = tan⁻¹...

4. ### Find the derivative of the function r(t), below. It may be to your advantage to simplify before differentiatin?

r = arcsin(4t) sin(r) = 4t cos(r) * dr = 4 * dt dr/dt = 4 / cos(r) dr/dt = 4 / sqrt(1 - sin(r)^2) dr/dt = 4 / sqrt(1 - (4t)^2) dr/dt = 4 / sqrt(1 - 16 * t^2) r'(t) = 4 / sqrt(1 - 16 * t^2)
