Step-by-step solution

4 steps
  1. Identify the trigonometric identity.

    The given expression is sin⁡π3cos⁡π6+cos⁡π3sin⁡π6\sin \frac{\pi}{3} \cos \frac{\pi}{6} + \cos \frac{\pi}{3} \sin \frac{\pi}{6}. This matches the sine addition formula:

    sin⁡(A+B)=sin⁡Acos⁡B+cos⁡Asin⁡B\sin(A+B) = \sin A \cos B + \cos A \sin B
  2. Apply the identity to the given expression.

    In this problem, A=π3A = \frac{\pi}{3} and B=π6B = \frac{\pi}{6}.
    Substitute these values into the formula:

    sin⁡(π3+π6)\sin\left(\frac{\pi}{3} + \frac{\pi}{6}\right)
  3. Calculate the sum of the angles.

    To add the fractions, find a common denominator:

    π3+π6=2π6+π6=3π6=π2\frac{\pi}{3} + \frac{\pi}{6} = \frac{2\pi}{6} + \frac{\pi}{6} = \frac{3\pi}{6} = \frac{\pi}{2}
  4. Find the value of sin⁡π2\sin \frac{\pi}{2}.

    We know that sin⁡π2\sin \frac{\pi}{2} is a standard trigonometric value:

    sin⁡π2=1\sin \frac{\pi}{2} = 1

    The final value is:

    sin⁡π3cos⁡π6+cos⁡π3sin⁡π6=1\sin \frac{\pi}{3} \cos \frac{\pi}{6} + \cos \frac{\pi}{3} \sin \frac{\pi}{6} = \boxed{1}
