Why are graphing calculators so much money?!

Pretty stupid that a calc class requires an 89. If anything they shouldn't be allowed in a calc class. SO many times have fellow classmaters had no clue wtf was going on yet kicked out answers with their 89s. Not that my 83+ wasn't ever useful for getting solutions when I didn't know what to do, but 89 is almost too easy!!

Wait. In your calc I through III classes, you can use a calculator?!?

Not in mine. I said you shouldn't be able to, especially an 89. Well I had Calc 1 in HS which we could use a calculator for. I would check my derivatives by graphing the numerical derivative against my answer since 83+ can only do numerical derivs. When I took Calc 1 and 2 in college we couldn't use one. Good choice by my instructor I'd say. I dont need to take Calc 3. My 83+ was helpful in Linear Algebra and some EE classes to solve simultaneous equations.

My TI-85 is a dozen years old and the price in the store is the same now as it was when I bought it. Seems like technology would make these cheaper. But, they just keep selling old goods at the same high price.

I have a financial calculator that looks 20 years old. It cost me $80.
