What is the central idea in Christine de Pisan's "City of Ladies," and why is it considered an early Feminist text? Are there any earlier Feminist texts that the author could have used as inspiration? Give an example if you have come across one in your reading.

The Cauchy-Schwarz Inequality Let u and v be vectors in R 2 .

We wish to prove that ->    (u · v)^ 2 ≤ |u|^ 2 |v|^2 .

This inequality is called the Cauchy-Schwarz inequality and is one of the most important inequalities in linear algebra.

One way to do this to use the angle relation of the dot product (do it!). Another way is a bit longer, but can be considered an application of optimization. First, assume that the two vectors are unit in size and consider the constrained optimization problem:

Maximize u · v

Subject to |u| = 1 |v| = 1.

Note that |u| = 1 is equivalent to |u| 2 = u · u = 1.

(a) Let u = a b and v = c d . Rewrite the above maximization problem in terms of a, b, c, d.

(b) Use Lagrange multipliers to show that u · v is maximized provided u = v.

(c) Explain why the maximum value of u · v must, therefore, be 1.

(d) Find the minimum value of u · v and explain why for any unit vectors u and v we must have |u · v| ≤ 1.

(e) Let u and v be any vectors in R 2 (not necessarily unit). Apply your conclusion above to the vectors: u |u| and v |v| to show that (u · v) ^2 ≤ |u|^ 2 |v|^ 2 .

A basis of a vector space V is a maximal linearly independent set of vectors in V . Similarly, one can view it as a minimal spanning set of vectors in V . Prove that any set S ⊆ V spanning a finite-dimensional vector space V contains a basis of V .

• Describe an experiment for electrostatic force and record your experiment with your phone.Describe your experiment and answer the following questions about each object:
• Is it a conductor or an insulator?
• Is it charged or neutral?
• If it is charged, describe how you charged it. Is it positively charged or negatively charged?
• If it is neutral, describe how it still attracted or repulsed by a charged object.
• You can answer these questions by either narrating your video, or by submitting a separate word file. There is no need to get fancy production wise unless you want to submit it to TikTok

You can choose either a repulsive interaction, or an attractive one.

Consider the following reduction potentials:

Mg2+ + 2e- → Mg

E° = -2.37 V

V2+ + 2e- → V

E° = -1.18 V

Cu2+ + e- → Cu+

E° = +0.15 V

Which one of the following reactions will proceed spontaneously?

• Mg2+ + V → V2+ + Mg

• Mg2+ + 2Cu+ → 2Cu2+ + Mg

• V2+ + 2Cu+ → V + 2Cu2+

• V + 2Cu2+ → V2+ + 2Cu+
