Evaluate the limit. \lim_{x \rightarrow \pi/2} \sin(x/2)-\cos(x/3)

Question:

Evaluate the limit.

{eq}\displaystyle \lim_{x \rightarrow \pi/2} \sin(x/2)-\cos(x/3) {/eq}

Limits:

We have a function which has sine and cosine terms. There are many methods to evaluate the limits like L hospital's rule, factorization, etc. Here we will directly apply the limits.

Answer and Explanation:

$$\lim_{x \rightarrow \pi/2} \sin(x/2)-\cos(x/3) \\ $$

We will directly apply the limits:

$$\sin(\pi/4)-\cos(\pi/6)\\ \frac{1}{\sqrt{2}}-\frac{\sqrt{3}}{2}\\ \frac{\sqrt{2}-\sqrt{3}}{2} $$
