To graph ( f(x) = \sin(x)  \sqrt{3}\cos(x) ) for ( x ) between ( [0, 2\pi] ):
 Identify the key points on the graph: the maximum, minimum, and points where the function crosses the xaxis.
 Calculate the values of ( f(x) ) at these key points.
 Plot the points on the graph.
 Sketch the curve connecting the points to form the graph of ( f(x) ).
Here are the steps:

Key points:
 Maximum: ( f(x) ) reaches its maximum when ( \sin(x) ) is at its maximum value of 1 and ( \cos(x) ) is at its minimum value of 1. So, ( f(x) = 1  \sqrt{3}(1) = 1 + \sqrt{3} ) when ( x = \frac{\pi}{2} ).
 Minimum: ( f(x) ) reaches its minimum when ( \sin(x) ) is at its minimum value of 1 and ( \cos(x) ) is at its maximum value of 1. So, ( f(x) = 1  \sqrt{3}(1) = 1  \sqrt{3} ) when ( x = \frac{3\pi}{2} ).
 Xintercepts: ( f(x) ) crosses the xaxis when ( \sin(x) = \sqrt{3}\cos(x) ). This occurs when ( \tan(x) = \sqrt{3} ), leading to ( x = \frac{\pi}{3} ) and ( x = \frac{4\pi}{3} ).

Calculate ( f(x) ) at the key points:
 ( f\left(\frac{\pi}{2}\right) = 1 + \sqrt{3} )
 ( f\left(\frac{3\pi}{2}\right) = 1  \sqrt{3} )
 ( f\left(\frac{\pi}{3}\right) = \sin\left(\frac{\pi}{3}\right)  \sqrt{3}\cos\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}  \sqrt{3}\left(\frac{1}{2}\right) = 0 )
 ( f\left(\frac{4\pi}{3}\right) = \sin\left(\frac{4\pi}{3}\right)  \sqrt{3}\cos\left(\frac{4\pi}{3}\right) = \frac{\sqrt{3}}{2}  \sqrt{3}\left(\frac{1}{2}\right) = 0 )

Plot the points: ( \left(\frac{\pi}{2}, 1 + \sqrt{3}\right) ), ( \left(\frac{3\pi}{2}, 1  \sqrt{3}\right) ), ( \left(\frac{\pi}{3}, 0\right) ), and ( \left(\frac{4\pi}{3}, 0\right) ).

Sketch the curve connecting the points to form the graph of ( f(x) ). The curve will oscillate between the maximum and minimum points, crossing the xaxis at the xintercepts.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
