Answer:
Step-by-step explanation:
Given
if tan x is equal to b by a then find the value of under root a + b by a - b + under root a minus b by a + b
ANSWER
So we have
tan x = b/a
√a + b /a-b + √a – b /a + b = a + b + a – b /√(a – b)(a + b)
= 2 a / √a^2 – b^2
= 2 / √a^2 – b^2 / a
= 2/√a^2 – b^2 /a^2
= 2/ √1 – (b/a)^2
= 2 / √1 – tan^2 x
= 2 cos x / √cos^2 x – sin^2 x
= 2 cos x /√cos2x
