how do I verify this problem?
1 answer:
Answer:
see explanation
Step-by-step explanation:
Consider the left side
Simplify the numerator/denominator using the trigonometric identities
• tanx =
and secx = 
sinx + tanx = sinx +
= 
=
← numerator
and
1 + secx = 1 +
=
← denominator
Putting this together gives
× 
Cancel cosx and (1 + cosx) on numerator/ denominator, leaving
left side = sinx = right side ⇒ verified

Sometimes...
2^-3 = 1/(2^3) = 1/8
-2^-3 = 1/(-2^3) = -1/8
