Question

Prove that:
Tan(A-B/2)/Tan(A+B/2)= (a-b)/(a+b)

Answer 1

Answer:

tan(a-b)/2/tan(a+b)/2

a-b/2/a+b/2. (tan is cancel to tan)

a-b/a+b ( 2 is cancel coz. it is in divide)

hence proved

hope it will help u

Answer 2

Answer:

Step-by-step explanation:

given= tan(A-B/2)/Tan(A+B/2)

now tan will be eliminated or cancelled from given equation

(A-B/2)/(A+B/2)

denomenater will be reciprocled after changing / in *

(A-B/2)*(2/A+B)

2 is eliminated or cancelled

(A-B)(A+B)
