Answer:
The image shows the graph for given function.
Step-by-step explanation:
We are given the following information in the question:

It is clear function is an exponential function and have shape similar to exponential function.
An exponential function is of the form:
,
where b is a parameter of the function and read as b raised to the power x.
The exponential function enjoys the following properties:
- If 0 < b < 1, then the graph decreases as we move from left to right.
- If b > 1, then the graph will increase as we move from left to right.
For the given equation ⇒⇒⇒

and the given range 0 ≤ x ≤ π
We should note that the zeros of the denominator will be at
cos x = 0
∴

So, the given equation is undefined at π/2
So, <span>the students error is the division by zero.

See the attached figure which represents the graph of the given equation and we can see it is undefined at π/2

Explanation:
You can calculate angular velocity in radians per second by using linear units.
That should be correct
Divide each side of the equation by 18. Then it will say 'm = a fraction'.
That's the solution. You can reduce (simplify) the fraction to make it look
neater.
