To solve this expression, we first need to find the values of each trigonometric function at the given angles.

sin(17π/6) = sin(2π + π/6) = sin(π/6) = 1/2

cos(14π/3) = cos(4π + 2π/3) = cos(2π/3) = -1/2

tan(13π/4) = tan(3π + π/4) = tan(π/4) = 1

Now, we can substitute these values back into the original expression:

sin(17π/6) + cos(14π/3) - tan(13π/4
= 1/2 - 1/2 -
= -1

Therefore, the value of the expression sin(17π/6) + cos(14π/3) - tan(13π/4) is -1.
