Answer:
Explanation:
We can start by simplifying the denominator, which is cot(a) + tan(a):
cot(a) + tan(a) = cos(a)/sin(a) + sin(a)/cos(a)
To combine these terms, we can find a common denominator of sin(a)cos(a):
cos^2(a)/(sin(a)cos(a)) + sin^2(a)/(sin(a)cos(a))
= (cos^2(a) + sin^2(a))/(sin(a)cos(a))
= 1/(sin(a)cos(a))
Now we can substitute this expression into the original equation:
sec(a)/(cot(a) + tan(a))
= sec(a) / (1/(sin(a)cos(a)))
= sec(a) * (sin(a)cos(a))
= (1/cos(a)) * (sin(a)/cos(a))
= sin(a)/cos^2(a)
= csc(a)sec(a)
Therefore, the simplified form of sec(a)/(cot(a) + tan(a)) is csc(a)sec(a).
