Here, fog(x) = 4x - 5 or, f(2x - 1) = 4x - 5 To find f(x), put x = (x + 1)/2, we get f{2(x + 1)/2 - 1} = 4(x + 1)/2 - 5 or, f(x + 1 - 1) = 2x + 2 - 5 or, f(x) = 2x - 3. Finally, gof(x) = 13 or, g(2x - 3) = 13 or, 2(2x - 3) - 1 .....
We know, 2A + A = 3A Opereting both sides by cot, cot[ A + 2A ] =cot3A or, [cotA cot2A - 1]/ [ cotA + cot2A] = cot3A or, [cotA cot2A - 1]= cot3A[ cotA + cot2A] or, cotA cot2A - 1= cot3A cotA + cot3A .....
Here, LHS =
=2tan(A - B)
=2{(tanA - tanB)/(1+tanA.tanB)}
Now substitute for tanA = 2tanB + cot B,
=2{(2tanB + cotB - tanB)/(1 + (2tanB + cotB).tanB)}
=2{(tanB + cotB)/(2 + 2tan2B)} (using .....
Here, Cot3θ = Tan6θ or, Cot3θ = Cot ( 90o - 6θ) [ since, cot(90- A) = tanA.] or, 3θ = 90o - 6θ or, 3θ + 6θ = .....
