1. Problem Description

We need to calculate the value of the expression sin(π6)+cos(π3)\sin(\frac{\pi}{6}) + \cos(\frac{\pi}{3}).

2. Solution Steps

First, we need to find the value of sin(π6)\sin(\frac{\pi}{6}). Recall that π6\frac{\pi}{6} radians is equal to 3030^{\circ}. We know that sin(30)=12\sin(30^{\circ}) = \frac{1}{2}. Therefore, sin(π6)=12\sin(\frac{\pi}{6}) = \frac{1}{2}.
Next, we need to find the value of cos(π3)\cos(\frac{\pi}{3}). Recall that π3\frac{\pi}{3} radians is equal to 6060^{\circ}. We know that cos(60)=12\cos(60^{\circ}) = \frac{1}{2}. Therefore, cos(π3)=12\cos(\frac{\pi}{3}) = \frac{1}{2}.
Now, we can substitute these values into the expression:
sin(π6)+cos(π3)=12+12\sin(\frac{\pi}{6}) + \cos(\frac{\pi}{3}) = \frac{1}{2} + \frac{1}{2}.
Adding these values together:
12+12=22=1\frac{1}{2} + \frac{1}{2} = \frac{2}{2} = 1.
