I remember back when I was an undergrad and taking all 3 semesters of calculus...graphing calculators had just come out or had become the "rage". Fortunately, I never had any calc teachers that insisted we learn stuff by the calculator - it was all on paper. And personally, I enjoyed learning it more that way than I would have by learning it on some fancy graphing calculator.

manny... my ap calc class in high school was big on calculators.. and frankly it put me at a disadvantage when I decided to retake calc in college with no calculator.. I think my high school just liked "technology" or something.. and I didn't realize it until later.. but you get to the point that you are just typing in stuff.. and you have no idea what it actually does... it's fine doing it on calc once you know what it is.. but otherwise.. can you imagine learning multiplication on the calculator from day 1, but never knowing what multiplication actually is..
don't get me wrong.. i love calculators... but i think it is better to learn by hand before learning it on a calculator..
well i was trying to go easy on him. i actually use stone tablets and scrape the problems in with my fingernails.
Calculator is the future now, yeah, you could be better off, and know really how to do it if you do it by hand, but come on, in the real world, there's just not enough time for you to do it by hand, and make mistakes. Just try to do 2.6^2.6 by hand, hahahaha...........
you cannot do implicit differentials on an 89. You can however do explicit it's like d(x^2+x,x) hit enter 2x + 1 for the second one, it's 4x^3 + 4y^3 dy/dx = 8(y+x dy/dx) (-4x^3 + 8y)/(4y^3 - 8x) = dy/dx That's easy stuff..
