AI Thread Summary

The discussion centers on the equation a = 4b / (6c - 5d) and the challenge of expressing variables A and B as fractions in their simplest form. The user successfully rearranged the equation to c = (A b/a) + Bd but is confused about the requirement to express A and B as fractions. There is uncertainty about whether the question is worded incorrectly, as the user has not encountered a similar problem before. The conversation highlights the difficulty in translating the initial equation into the desired format. Clarification on the expression of A and B is sought to resolve the confusion.

I did the first section of the question. I rearranged a = 4b / (6c -5d) to be c = (A b/a) + Bd

but then it says express A and B as fractions in their simplest form. Is the question worded wrong? I've never seen anything like this before?

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
