Basic Algebra: tan δ = 1/wCR | Confirmation Needed

AI Thread Summary
The discussion centers on the equation tan δ = 1 / wCR, questioning its validity and the derivation process. Participants express confusion over the relationship between the variables and whether dividing the equations yields R/wC instead. Clarification is sought on the correct mathematical manipulation, with one participant confirming that the division leads to a different result. The conversation highlights the importance of showing work in algebraic derivations for better understanding. Overall, the thread emphasizes the need for clear mathematical reasoning in confirming equations.

why has our lecturer put tan δ = 1 / wCR ?

if you divide the two equations to get tan wouldn't it be R/wC ?

thanks for any conformation

you're right, too much revision, can't think straight!

(-1/wc) / (R/1) = (-1/wc) * (1/R) = (-1/wRc)
 

Thread 'Family of lines that are at a distance of 5 from the origin'

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...
