If y is inversely proportional to (tan x) and y = 2 when x = 30°, find the value of y when this value
of x is doubled.​

Step-by-step explanation:

y is inversely proportional to tan x means  

Given y = 2 when x =30° . So we will find k.

Now x is doubled, x = 60°, find y

there are no short passages to look at

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
