Answer: 2
Step-by-step explanation:
Taking thetha as x for convenience
tanx = 3/4
As we know sec^2(x) = tan^2(x) + 1
Therefore, sec^2(x) = 9/16 + 1 = 25/16
=> sec^2(x) = (5/4)^2 => sec(x) = 5/4
Now divide the numerator by cos(x)
We get
(tanx - 1 + secx)/(tanx + 1 - secx)
= (3/4 - 1 + 5/4)/(3/4 + 1 - 5/4)
= (4/4)/(2/4) = 2
