Give sin x = 3/5 and x is in qudrant 2, what is the value of tanx/2?

tan x/2 = 3.

Step-by-step explanation:

The adjacent side in the second quadrant of the unit circle = - sqrt (5^2 - 3 ^2)

= - 4, so cos x = - 4/5.

Using the formula tan x/2 = sin x / (1 + cos x) we have

tan x/2 = 3/5 / (1 - 4/5)

= 3/5 / 1/5

= 3 (answer).
