Trigonometric functions use degree as their default unit. For radian measure, add rad following the first value in an expression. So e.g. cos(45) is the same as cos(pi rad / 4). Expressions in degrees can use either deg or &deg;, e.g. 360deg-atan2(3; 4) or 360&deg;-atan2(3; 4). If an expression is without units and needs to be converted to degrees or radians for compatibility, multiply by 1deg, 1&deg; or 1rad as appropriate, e.g. (360-X)*1deg; (360-X)*1&deg;; (0.5+pi/2)*1rad. These trigonometric functions are supported:
