The trigonometric functions like cos/sin/tan ... expect arguments in radians, not in degrees, so "sin (pi*90/180) should give the expected answer.

Closing report.

Hi,
I have a problem about calculating cos(x) and sin(x), in command window. For instance, When I enter the sin(90) it calculate 0.89 but correct answer is 1. Can you help me for this problem.
