# Manuals/calci/THETAS

• is the number of parts into which the 360 degree rotation of a circle is to be divided,
• is the number of times the pattern has to be repeated,
• value decides whether the angle is to be displayed in radians or in degrees.

## Description

• This function divides the 360 degree rotation of a circle in mentioned number of parts and repeats the parts with mentioned number of times. Angle is displayed in radians or in degrees depending on the value of .
• Theta or is a variable that stands for angle in geometry and trigonometry.
• The value of can be either '1' or '0'. '1' indicates angle in radians. '0' indicates angle in degrees.
• 1 degrees = 0.0174532925 radians.
• If not mentioned, the default value for is 1.
• and should be positive numbers. Else Calci gives an error message.

## ZOS

• The syntax is to calculate THETAS in ZOS is THETAS(Parts,Times,InRadians).
• e.g THETAS(4,2,1) displays 0 1.5707963267948966 3.141592653589793 4.71238898038469 6.283185307179586 7.853981633974483 9.42477796076938 10.995574287564276 12.566370614359172

Here 360 degree rotation is divided into 4 parts and is repeated one more time for further 4 angles.
