(1÷sinA-1÷cosA) ( cosA÷sinA-sinA÷cosA)

(cosA-sinA÷sinA cosA) (cos2A(here square)-sin2A)÷sinA cosA

(cosA-sinA)(cosA-sinA)(cosA+sinA)÷ (sinAcosA)2
(cosA-sinA)2 (cosA+sinA)÷(sinAcosA)2

cos2A+sin2A-2×(cosAsinA)
here cos2A+sin2A=1
(1-2sinAcosA)(cosA+sinA)÷(sinA cosA)(sinAcosA)
(sinAcosA1-2)÷(sinAcosA) (sinA+cosA)÷sinAcosA).
