domain of-tan(x)

domain

- tan (x)

πn \leq x < \frac{π}{2} + πn or \frac{π}{2} + πn < x < π + πn

Solution steps

Take the denominator(s) of

- tan (x)

and compare to zero:

x = \frac{π}{2} + πn

Periodicity of

- tan (x) : π

Combine period:

πn \leq x < π + πn

and undefined points.

The domain is

πn \leq x < \frac{π}{2} + πn or \frac{π}{2} + πn < x < π + πn

m = \infty, (0, \frac{- 5}{2})

7 x + 6 y = - 17

- t^{3} + 21 t^{2} + 35 t + 20

f (y) = 2 x + 3

6 x^{2} - 15 x
