(cosecA+cotA) (1--cosA)=

• Ans:
  sin A
  w.k.t,
  cosecA=1/sinA; cotA=cosA/sinA;
  (cosecA+cotA)(1--cosA)=cosecA-cosecAcosA+cotA-cotAcosA
  =cosecA-(cosA/sinA)+cotA-(cos^A/sinA)
  =cosecA-cotA+cotA-(cos^2 A.cosecA)
  =cosecA(1-cos^2 A)
  =cosecA(sin^2 A)
  =(sin^2 A)/sinA
  =sinA.

• (cosecA+cotA)(1-cosA)=cosecA(1+cosA)(1-cosA)
  =cosecA(1-cos^2A)
  =cosecA(sin^2A)
  =sinA

• cosecA+cotA*1-cosA=(1/sinA+cosA/sinA)*sinA=sinA+cosA
