EXERCISES FOR SECTION 6.3 1. Suppose that the functions f, g, f², g², and fg are integrable on the closed bounded interval [a, b]. Prove that [f-g]² also is integrable on [a, b] and that $\int_a^b [f-g]^2 \ge 0$. Use this to prove that $$ \int_a^b fg \le \frac{1}{2} \left[ \int_a^b f^2 + \int_a^b g^2 \right]. $$

6 -2 Consider the quadratic form $q_A(x, y) = \vec{x}^T A \vec{x}$ where $A = \begin{bmatrix} -2 & 9 \end{bmatrix}$. For the transformation $T: \mathbb{R}^2 \to \mathbb{R}^2$ with standard matrix: $\begin{bmatrix} 1 & 0 \ 0 & 4 \end{bmatrix}$ $P = $ (i.e. a vertical stretch by a factor of 4), find the transformed quadratic form $q_B(x, y)$ obtained from $q_A$ via $T$. q_B(x, y) = where: $B = \begin{bmatrix} & \ & \end{bmatrix}$

Q4) Determine if each statement is true or false. If false, correct/rewrite the statement which is underlined to make it true. Answer ten only! 1- In a heat treatment of steels by carburization the carbon is trapped on steel surface by Vacancy diffusion. 2- The concentration gradient in steady-state diffusion is the rate of change of concentration with respect to time. 3- The relation between diffusion coefficient and temperature is linear. 4- Completely liquid phase exist for all compositions in a phase diagram above the solidus line. 5- The relative fractions of phases at a given temperature for an alloy composition Co is obtained by Gibbs phase rule 6- Cu-Ni phase diagram is an example of unary phase diagrams. 7- A large activation energy results in a large diffusion coefficient. 8- The following plot shows the concentration profiles at different times. Fick's first law is applicable for this phenomenon. To represent it mathematically, Fick's first law is applied. Two initial conditions and one boundary condition are needed to solve it analytically. 9- Sublimation region is the region where the liquid and vapor phases are at equilibrium 10- In the diffusion phenomenon, the lower concentration difference, the higher the diffusion rate. 11- In the isomorphous phase diagram, the phase of the alloy below the solidus curve is completely liquid. 12- The range of freezing of an alloy is above the liquidus curve.
