Answer:
cotAcosA/cotA+cosA
=[(cosA/sinA)cosA]/[(cosA/sinA)+cosA]
=(cos²A/sinA)/[(cosA+sinAcosA)/sinA]
=cos²A/cosA(1+sinA)
=cosA/(1+sinA)
=[cosA(1-sinA)]/[(1+sinA)(1-sinA)]
[multiplying the numerator and the denominator with (1-sinA)]
=[cosA(1-sinA)]/(1-sin²A)
=(cosA-cosAsinA)/cos²A
=[(cosA-cosAsinA)/sinA]/(cos²A/sinA)
[dividing the numerator and the denominator by sinA]
=[(cosA/sinA)-(cosAsinA/sinA)]/(cosA/sinA)cosA
=(cotA-cosA)/cotAcosA
Hope so it will help:))
