UPDATE YOUR GDC
If you do not have Version 4.4 then you're missing out...
To check the version of your GDC, on the homepage go to ‘Settings’ > ’Status’.
If the Version is earlier than 4.4…. you may not have access to relation sketching and the invbinom function. To update your TINSpire, first download this file and save it somewhere that you can find easily. 1. Connect your handheld to your computer using one of the long USB cables 2. Open up the TINspire 'Student software’ provided in the GDC box when you were given the calculator, or download the free ‘Computer Link Software’ from here. 3. When the handheld is connected go to ‘Tools’ > ’Install Handheld/Lab cradle OS’ and select the file from your documents. 4. Enjoy your rejuvenated, state of the art GDC!
