Use fundamental identities to simplify the expression

sinx+1 + 1/sinx-1

  • calculus -

    surely you must mean

    sinx + 1 + 1/(six- 1)
    if so , then

    the LCD is sinx - 1
    and we get
    ( (sinx +1)(sinx - 1) +1) )/(sinx - 1)
    = sin^2 x - 1+ 1)/(sinx + 1)
    = sin^2 x /(sinx + 1)
