b) \( \sum_{n=1}^{\infty} \frac{n}{n^{2}+1} x^{n}, x>0 \) b) \( \sum_{n=1}^{\infty} \cos \frac{1}{n} \)
X\(_1\), X\(_2\), X\(_3\), and X\(_4\) are normally distributed random variables: X\(_1\) ~ N(0,0), X\(_2\) ~ N(0,1), X\(_3\) ~ N(1,0), and X\(_4\) ~ N(1,1). The variable(s) which follow(s) a standard normal distribution is (are)
Factor the following polynomial into linear irreducible factors: •P (x) = (x - \sqrt{6}i) (x + \sqrt{6}i) (x - \sqrt{5}i) (x + \sqrt{5}i) P(x) = (x - \sqrt{6}) (x + \sqrt{6}) (x-\sqrt{5}i) (x + \sqrt{5}i) P(x) = (x - \sqrt{6}i) (x + \sqrt{6}i) (x-\sqrt{5}) (x+\sqrt{5}) P(x) = (x - \sqrt{6})^2 (x - \sqrt{5})^2 P(x) = (x - \sqrt{6}) (x+\sqrt{6}) (x-\sqrt{5}) (x+\sqrt{5}) None of the above P(x) = x^4 + 11x^2 + 30
The text appears to be free of spelling, typographical, grammatical, OCR, and mathematical errors. However, the formatting is not consistent and there are missing parentheses and semicolons in the code. Additionally, there are some missing spaces and incorrect indentation in the code.
3. A solid conducting sphere carrying net charge Q has radius a. a. Derive or state an expression for the electric field at a distance $r < a$. (1 point) b. Derive or state an expression for the electric field at a distance $r > a$. (1 point) c. On the diagram below, sketch the electric field as a function of r. (3 points)
Text: Discuss briefly the contributions to overpotential in an electrolysis reaction. Describe the effect of mass transport on the current in an electrolysis reaction, sketching the shape of a current-potential curve for diffusion-limited single-electron reduction of a metal cation (e.g. Fe(III)), showing the difference in curve shape for a process of high versus low exchange current density.
