Description
sin(θ) returns the sine of θ, which is defined as the y-value of the point of intersection of the unit circle and a line containing the origin that makes an angle θ with the positive x-axis
The value returned depends on whether the calculator is in Radian or Degree mode. A full rotation around a circle is 2π radians, which is equal to 360°. The conversion from radians to degrees is angle180/π and from degrees to radians is angleπ/180. The sin( command also works on a list of real numbers.
In radians:
sin(π/6)
.5
In degrees:
sin(30)
.5
Advanced Uses
You can bypass the mode setting by using the ° (degree) and ʳ (radian) symbols. These next two commands will return the same values no matter if your calculator is in degrees or radians:
sin(30°)
.5
sin(π/6ֿ¹)
.5
Error Conditions
- ERR:DATA TYPE is thrown if you supply a matrix or a complex argument.
- ERR:DOMAIN is thrown if you supply an input ≥1E12.
