Engineers frequently need to find where an equation equals zero (roots) or where it reaches its maximum/minimum value (optimization).

If an assignment is ambiguous or the autograder keeps failing your code, check the course forums. Mentors and peers frequently post threads detailing common pitfalls, clarifying grading criteria, and providing hints without giving away code.

If you are stuck on a specific Coursera problem, do not look for the direct answer key. Instead, use these tools to diagnose where your math or code is going wrong:

Used when data contains error. It fits a trendline (linear or polynomial) that minimizes the overall residual energy.
