Step-by-step explanation:

Solution

tanA−secA+(sec

A−tan

A)

tanA+secA−1

=

tanA−secA+(secA−tanA)(secA+tanA)

tanA+secA−1

=

(tanA−secA)(1−secA−tanA)

tanA+secA−1

=

−(tanA−secA)(secA+tanA−1)

tanA+secA−1

=

secA−tanA

=tanA−secA+(secA−tanA)(secA+tanA)

tanA+secA−1

=(tanA−secA) (1−secA−tanA)

tanA+secA−1

=−(tanA−secA)(secA+tanA−1) tanA+secA−1

=secA−tanA1

=cosA1−cosAsinA1

=1−sinAcosA

=1−sinAcosA×1+sinA1+sinA

=1−sin2AcosA(1+sinA)

=cos2AcosA(1+sinA)
