Operation Manual
Typically, a result is calculated by entering a number and then selecting the appropriate
math function. For example, to enter a
RADIUS whose value is the square root of 2,
press the 2 key, the CALC key and then select the SQR ROOT softkey. A value of
1.4142 (the square root of 2) will be displayed.
Trig functions are calculated by entering the angle first and then the appropriate trig
function. For example, enter 30 , then select the SIN softkey. A value of 0.5000 ( SIN
30° ) will be displayed.
Typically, a trig value must be multiplied by another number to calculate an actual
dimension. In the example above, assume the 0.5000 must be multiplied by the length of
a triangle's hypotenuse, say 4, to calculate the side opposite the 30° angle.
