Questions & Answers

Q: How do you find del u by del x with y treated as constant?

To find del u by del x with y as constant, we partially differentiate u with respect to x, resulting in a value of a.

Q: How is del y by del v calculated while treating x as constant?

Del y by del v, treating x constant, is derived by differentiating y with respect to v, yielding -1/a as the result.

Q: Why is it important to eliminate variables in solving partial differentiation problems?

By eliminating variables like y or x when unnecessary, it simplifies calculations and helps derive expressions for functions like v or x in terms of other variables.

Q: How is the final answer of 1 obtained in the problem solving?

By multiplying the calculated values of del u by del x, del x by del u, del y by del v, and del v by del y, the product simplifies to 1, revealing the final answer.
