uStop Line Example

The following screen shows how you can use stop lines to group calculation steps.

A

B

A:Substituting a value ( 6π here) for θ in the expression in line 1 executes (sinθ)2 + (cosθ)2 in line 3, and displays the result in line 4 (1). In this example, substituting any value in line

1 and pressing w will produce a result of 1.

If we wanted to test various values for θ without recalculating all of the math lines

underneath it, we could insert a stop line at the location shown above. Then, each time we change the value of θ and press w, the calculator will re-calculate (sinθ)2 + (cosθ)2

and then stop.

B:These math lines are not required to test various values for θ.
