Question

any body help me Dom ( tan(x) )

Answer 1

The domain is the range of x values, and f(x)=tan(x) is periodic in x with period Pi

Answer 2

tan (x)= sin(x)/ cos (x) ,,,there is a restriction on cos (x) i think ??

Answer 3

Yes, \(x\not=\dfrac{n\pi}{2}\), since this makes the denominator 0.

Answer 4

meaning \(x\) can't be \(\dfrac{n\pi}{2}\) for integer \(n\); otherwise, \(\cos x=0\) and \(\tan x=\text{undefined}\).

Answer 5

but can we write the solve like this n*180/2*n

Answer 6

In degrees it would be \((180n)^\circ\)
