Answer 2

I can help you with your math problem. The expression you want to find the value of is $$\sin^2 45^\circ + \tan 60^\circ \cdot \cos 30^\circ$$

To simplify this expression, we can use the following facts:

- $\sin 45^\circ = \cos 45^\circ = \frac{\sqrt{2}}{2}$ - $\tan 60^\circ = \frac{\sqrt{3}}{1}$ - $\cos 30^\circ = \frac{\sqrt{3}}{2}$

Using these facts, we can rewrite the expression as:

$$\left(\frac{\sqrt{2}}{2}\right)^2 + \frac{\sqrt{3}}{1} \cdot \frac{\sqrt{3}}{2}$$

Simplifying further, we get:

$$\frac{1}{2} + \frac{3}{2}$$

Adding the fractions, we get the final answer:

$$\frac{4}{2} = 2$$

Therefore, the value of the expression is 2. I hope this helps you. Have a nice day.
