HP Prime Graphing NW280AAABA manual Specify the known values

Set angle measure

2.If there is unwanted data from a previous calculation, you can clear it all by pressing SJ(Clear).

Make sure that your angle measure mode is appropriate. By default, the app starts in degree mode. If the angle information you have is in radians and your current angle measure mode is degrees, change the mode to degrees

before running the solver. Tap or

depending on the mode you want. (The button is a toggle button.)

N o t e The lengths of the sides are labeled a, b, and c, and the angles are labeled A, B, and, C. It is important that you enter the known values in the appropriate fields. In our example, we know the length of two sides and the angle at which those sides meet. Hence if we specify the lengths of sides a and b, we must enter the angle as C (since C is the angle where A and B meet). If instead we entered the lengths as b and c, we would need to specify the angle as A. The illustration on the screen will help you determine where to enter the known values.

Specify the known values

3.Go to a field whose value you know, enter the value

and either tap or press E. Repeat for each known value.

(a). In a type 4 and press

E.

(b). In b type 6 and press

E.

(c). In C type 30

and press E.
