Eight reviews of the mechanism
Threshold: 7 out of 8. without a timer. Balls are given for answers, not for visits. This is a local self-check; the decisions will be shown after dispatch.
1. What does shape [4096] mean?
4096 axis of the array
One axis, 4096 coordinates
4,096 different bases
2. When the base of the same vector changes, what changes?
His world situation is binding.
Coordinates regarding the new base
Size of space mandatory
3. Why is the L2 square not the norm?
It could be negative.
It's always zero.
On a scale of 2 grows four-fold.
4. What gives a dot two n-vectors?
Scalar
Vector of Unproductions
Matrix[n,n]
5. L2 vectors[3.4]?
Your numerical response
6. Dot [1.2] and [3.4]?
Your numerical response
7. First projection coordinate [3.4] to [2.0]?
Your numerical response
8. At B=[1.1],[0.1]],x=[3.4] the first co-ordinate B-1x?
Your numerical response
The result will appear after all the answers have been sent.
Research and explain
Compare y and -y: explain why cosine changes the sign and the projection on their line is retained. Repeat with zero y and explain the message to the lab.
First, shape the hypothesis, then change one parameter. Compare the numbers to the formula; state the extreme case and the limit of applicability. The free conclusion is not evaluated by a dummy automatic score.
