L. H. S. = Sec2A+cosec2A
= 1/cos2A+1/sin2A
= sin2A+cos2A/cos2A×sin2A
= 1/cos2A×1/sin2A. (sin2A+ cos2A= 1)
= sec2Acosec2A = R. H. S
A= theta, sec2A= sec square A, cosec2A= cosec square A.
= 1/cos2A+1/sin2A
= sin2A+cos2A/cos2A×sin2A
= 1/cos2A×1/sin2A. (sin2A+ cos2A= 1)
= sec2Acosec2A = R. H. S
A= theta, sec2A= sec square A, cosec2A= cosec square A.
