prove(sinx/cosx+1)+(cosx-1/sinx)=0
Please help asap!!!!! PLEASE

  • Trig - ,

    I think you mean

    sin x/(cos x + 1) + (cos x-1)/sin x = 0
    multiply both sides by sin x (cos x+1)
    sin^2x + (cos x-1)(cos x+1)= 0
    sin^2 x + cos^2 x - 1 = 0
    but we know sin^2 x+cos^2 x = 1
    1 - 1 = 0
