Let $f : [0, 1] \to [0, 1]$ be continuous. Prove that there exists $a \in [0, 1]$ such that $f(a) = a$. In other words, such a function must have at least one fixed-point on its domain. (Hint: Consider the function $g(x) = f(x) - x$.)

3. Prove the following equations where $\bar{X} = \frac{1}{n}\sum X_i$ and $\bar{Y} = \frac{1}{n}\sum Y_i$. (a) $\sum (X_i - \bar{X}) = 0$ (b) $\sum (X_i - \bar{X})^2 = \sum X_i^2 - n\bar{X}^2$ (c) $\sum (X_i - \bar{X})X_i = \sum (X_i - \bar{X})^2$ (d) $\sum (X_i - \bar{X})\bar{Y} = 0$
Consider the series \begin{equation*} \sum_{n=1}^{\infty} \frac{n}{3n+9} \end{equation*} Determine whether the series converges, and if it converges, determine its value. Converges (y/n): Value if convergent (blank otherwise):
S A small particle of mass \( =m \) is pulled to the top of a thitionless half-cylinder corn? that \( R^{2} \) by a light cond thasses over the top of the cylinder as illusrated in Figure P7.15. (a) Assuming the particle moves at a constant speed, show that \( F=m g \cos \theta \). Note: If the particle moves at constant speed, the component of its acceleration tangent to the cylinder must be zero at all times. (b) By directly integrating \( W=\overrightarrow{\boldsymbol{F}} \cdot d \overrightarrow{\mathrm{r}} \), find the work done in moving the particle at constant speed from the bottom to the top of the half-cylinder. 21. A 0.600 - V kinetic energy on the 22. A 4.00 V positio at \( x= \) and \( (c \) 23. A 210 T grour
The two fields arriving at Young's Double slit may be represented by $\vec{E}_1 = \vec{E}_{01} \cos(\vec{k}_1.\vec{r} - \omega t + \phi_1)$ and $\vec{E}_2 = \vec{E}_{02} \cos(\vec{k}_2.\vec{r} - \omega t + \phi_2)$. Deduce an expression for the resultant intensity on the screen, clearly demonstrating the conditions for the different types of interferences.
