Does anyone know if graphing calculators are necessary for engineers in the Swanson school of engineering. What kind would you recommend? I’m looking at TI-86 and TI-89. Not sure which would be best.
We are wondering the same thing. Would like to have it purchased before arriving on campus.
Definitely get the TI-89
Thank you, AwesomeOpossum! I told my student you steered us to Razzy Fresh, you have great credibility! 
Check Staples, they offered a rebate on the one we bought D last year for AP Calc.
