Simple basic algebra

  1. May 14, 2014 #1
    please see attached image

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

    if you divide the two equations to get tan wouldnt it be R/wC ?

    thanks for any conformation

    you're right, too much revision, cant think straight!

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