Use

The Cos() function returns the cosine of an angle. The input must have an angular unit, but unitless is acceptable and will be treated as radians.

Cos() works with complex numbers.

Examples of trig functions

• Cos(0.5)  = 0.878
• Cos(0.5 rad)  = 0.878
• Sin(45 deg)  = 0.707
• Tan(1 + i)  = 0.272 + 1.0839i
• Tan((60 + 30i) deg)  = 0.787 + 1.135i
