Activity 1 Step 1. For Y1 = sin x, should the Y1 be a capital Y with dot 5 1 as in print? In Activity 2 Step 1 a lower case y with subscript 1 is used and this seems to be consistent with other graphing calculator activities. The narrative often shows both and I have been following the print. Just curious if there's a standard way to show it in Braille. Also in the KEYSTROKE examples, when the keystroke is Y= do you omit the space between Y and equal as in print? For KEYSTROKE X,T,(theta),n do you omit the spaces after the commas as in print? Thanks for your help
First, let me apologize for the delay in answering your questions. I actually took a vacation. My answers will be suggestions only (for the time being). BANA is in the process of finalizing a set of guidelines for graphing calculators.
Y1 = sin x Yes, capital y followed by dot 5 number 1 as in print. Boldface should be indicated in braille. As for the two different ways of expressing y sub 1, follow print. In the keystroke Y=, do not insert a space between the Y and the equal sign. In keystroke X,T,(theta),n insert a space following each comma.
