the graphing calculators are differentiated exactly by being able to do analytical solutions. they run the equivalent of derive, mathematica, and wolfram alpha. you're paying for the software, and similar software for your pc costs more. in many other countries, they are simply unavailable. in the real world, if you have a bunch of differential equations, you want to not spend time solving them for the hundredth time and work on the actual physics problem. to give you an example with a non-graphing calculator you seem to confuse the TIs with: why need a calculator for numerical solutions, in your 12th year of school. let's take the multiplication of three 7 digit numbers, and multiply it out by hand. oh, you've done it a thousand times already and it's not bringing value? nah, you should be multiplying them out - the 1001st time will somehow still help you learn. I know how to take a derivative. I can look up the template it fits into, plug in my equation, and 5 minutes later I got it. This teaches me nothing after the first hundred times. And no, that derivative is not a number. We have limited time. We want to spend it on learning new analytical problem solving. Not doing repetitive busywork. >like CS for example if you are going to compare it, the apt comparison would be a CS degree taught for 4 years only in assembly. Here in the real world, we use tools to not do useless tasks.
