Prove that

Thank you! :)

  • Trigonometry -

    LS = sinx/cosx + cosx/sinx
    = (sin^2 x + cos^2 x)/sinxcosx
    = 1/(sinxcosx)
    = 2/(2sinxcosx)
    = 2/sin (2x)
    = 2csc (2x)

    Your RS = 2sec(2x) which is incorrect

    Did you have a typo?

    Yes I had a typo. Thank you!!

    (I don't know how to respond to answers besides this....)
