What is cscX – cotX? ?

3 Answers

• cscx=1/sinx

  cotx=cosx/sinx

  1/sinx-cosx/sinx=(sinx*(1-cosx))/(sinx)^2

  (sinx-sinx*cosx)/(sinx)^2 =

  (sinx)^2=1-(cosx)^2

  sinx*(1-cosx)/(1-(cosx)^2)

• Cscx Cotx

  (cotx)/(cscx-1)=(cscx+1)/(cotx) LS = cot(x) / (csc(x)-1) * (csc(x)+1) / (csc(x)+1) = cot(x)(csc(x)+1) / (csc^2(x) – 1) = cot(x)(csc(x)+1) / cot^2(x) = (csc(x) + 1) / cot(x) Hence proved
