Question

If tan theta is 12/5 then find value of 1 +sin theta/1-sin theta

Answer 1

Step-by-step explanation:

tan u =12/5

then tan u= p/b=12/5

=> p=12 & b= 5

so by pythagoreas theoram

h= 13

now, sin u = p/h = 12/13

now, 1+ sin u = 1+(12/13) = 1.92

and, 1- sin u = 1-(12/13) = 0.08

hence (1+ sin u)÷(1- sin u ) = 1.92÷ 0.08 = 24

hence proved
