sin(0.5) + sin(pi + 0.5) - tan(5) * cot(5)

To calculate the value, we first need to convert pi (π) into degrees, which is equal to 180 degrees.

sin(0.5) = 0.479
sin(pi + 0.5) = sin(180 + 0.5) = sin(180) = 0
tan(5) = -3.38
cot(5) = 0.29

Now we substitute these values into the given expression:

0.479 + 0 - (-3.38 * 0.29)
= 0.479 + 0 + 0.9792
= 1.4582

Therefore, the value of sin(0.5) + sin(π + 0.5) - tan(5) * cot(5) is approximately 1.4582.
