Question

(sec A + tan A) (1 - sin A) is equal to
a)sec A
b)sin A
c)cosec A
d)cos A​

Answer 1

Answer:

Cos A

Step-by-step explanation:

(sec A + tan A)(1 - sinA)

=(1/cos A + sin A/cos A) (1 - sinA)

={(1 + sinA)/cosA} (1 - sinA)

=(1 + sinA) (1 - sinA)/cosA

=(1 - $Sin^{2} A$)/cosA

=($cos^{2} A$)/cos A

=cos A
