= sin(pi)cos(pi)/5 + 4cos(pi/3)sin(5pi/2)
= 0 0 /5 + 4 (-1/2) * 1
= 0 + 4 * (-1/2)
= 0 - 2
= -2
Therefore, sin(pi)cos(pi)/5 + 4cos(pi/3)sin(5pi/2) = -2.
= sin(pi)cos(pi)/5 + 4cos(pi/3)sin(5pi/2)
= 0 0 /5 + 4 (-1/2) * 1
= 0 + 4 * (-1/2)
= 0 - 2
= -2
Therefore, sin(pi)cos(pi)/5 + 4cos(pi/3)sin(5pi/2) = -2.
