To find:

The exact value of tan(195°).

Solution:

We have,

It can be written as

Therefore, the exact value of tan(195°) is .

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
