Minimum questions

This section presents the questions you need to know the answer to in order to to follow the course.

1. Is it possible to multiply a vector by a vector?

• Yes, there are several ways to do it - scalar, vector product.
• No, you have to multiply a vector by a matrix or a number.
• No, it works differently for vectors.
• Yes, we multiply each component of a vector by each other. This is called scalar product.

2. Can the norm of a matrix be zero?

• Yes
• No

3. What is the derivative of the function $f(x) = x^2$?

• $2x$
• $2x + const$
• $\frac{x^3}{3}$
• $\frac{x^3}{3} + const$
• There is no way to take the derivative.

4. What is the antiderivative (indefinite integral) of the function $f(x) = x^2$?

• $2x$
• $2x + const$
• $\frac{x^3}{3}$
