step 3:22-7=15
Answer:
Below.
Step-by-step explanation:
Convert to sin's and cos's:-
(secx + tanx)(1-sinx)/cosx)
= ( 1/ cos x + sinx / cos x) * ( 1 - sin x )/ cos x)
= (1 + sin x) / cos x) * ( 1 - sin x ) / cos x
= (1 - sin^2 x) / cos^2 x
But 1 - sin^2 x = cos^2 x
so we have
cos^2 x / cos^2 x which = 1.
