### Assignments

• All assignments due on Saturdays before 5 PM.
• Late assignments will be marked zero.
• There will be both written and computational part in the assignments.
• Students need to submit their assignments in IPython/Jupyter notebooks through the dropbox link provided.
• The name of the Python notebook should be as follows: ma14m093_5.ipynb, where ma14m093 is your roll number and 5 implies that you are submitting your fifth assignment.
• Students need to submit their assignments in IPython/Jupyter notebooks through the dropbox link provided.
• Any copying on assignments will result in a zero on the assignment.
• We will be using JPlag to detect similarities among multiple sets of source code files.
• The grader will expect you to express your ideas clearly, legibly, and completely, often requiring complete English sentences rather than merely just a long string of equations or unconnected mathematical expressions. This means you could lose points for poorly written proofs or answers. Clear exposition is a crucial ingredient of technical communication. Clarity of thought and presentation is more important in mathematics & sciences than any other field. The only way to master exposition is by repeated practicing.
