Verify that the building block solution for the stream function \(\psi = C \frac{[\sin\theta]}{r}\) satisfies the conservation of mass, irotationality, and the Laplace's equation for incompressible flow. Do the calculations in the polar coordinate system. For example, you will find the velocity field \(V_r\) and \(V_\theta\) in the polar coordinate system and use these in the conservation of mass and irrotationality conditions.

6.(A)(a) One root of the equation $3^x + x^2 = 9$ lies between a=1.0 and b=2.0. Use the method of bisection four times to find a better approximation of this root. (Note: Carry seven significant digits in your calculations). (b)Use the following iterative formula once to find a better approximation of the root of the equation given in (a). Take as an initial value the final result you obtained in (a). (Note: Carry seven significant digits in your calculations). $x_{n+1} = x_n - \frac{f(x_n)}{f^{(1)}(x_n) - \frac{f(x_n)f^{(2)}(x_n)}{2f^{(1)}(x_n)}}$ [Hint: Let $f(x) = 3^x + x^2 - 9$. Note that $f^{(1)}(x)$ represents the first derivative of f(x). Similarly $f^{(2)}(x)$ represents the second derivative of f(x)]. 6.(B) Consider the equation $x^3 - 6x^2 + 9x - 3 = 0$.This equation can be transformed into the form x = F(x) in several ways. Find a suitable form and use fixed-point iteration six times to find a better approximation to the root that is close to $x_0 = 1.6$.(Note: Carry seven significant digits in your calculations).

Consider the force $F$ acting at an angle of $\theta = 30.0^\circ$ on a uniform rod with a mass $m = 122.46$ g and length $d = 40.6$ cm, as indicated on the diagram below. The other end of the rod is attached to a wall at point A by means of a hinge. The system is in static equilibrium. The magnitude of the force $F$ (in N) needed to keep the rod horizontal, is equal to: Neem die waarde van die gravitasieversnelling as $g = 9.80 \text{ ms}^{-2}$ Use the value of the gravitational acceleration as $g = 9.80 \text{ ms}^{-2}$.
