The trigonometric form of the complex number given in the task content is; 18(isin(π/2)).
<h3>What is the trigonometric form of the complex number?</h3>
If follows from the task content that the complex number whose trigonometric representation is to be determined is; 18i.
Hence, It follows that the trigonometric form is;
= 18(cos(π/2) + isin(π/2)). where; cos(π/2) = 0.
Hence, we have;
= 18(isin(π/2)).

Answer:
Answer:
f(g(x)) = g(f(x)) = x and f and g are the inverses of each other.
Step-by-step explanation:
Here, the given functions are:
To Show: f (g(x)) = g (f (x))
(1) f (g(x))
Here, by the composite function:
⇒ f (g(x)) = x
(2) g (f(x))
Here, by the composite function:
⇒ g (f(x)) = x
Hence, f(g(x)) = g(f(x)) = x
⇒ f and g are the inverses of each other.
I think x = 2 is the answer
