    Try wolframalpha. If you have a trial account or the app on your phone it will tell you how to solve them.

    Couldn't do the ones with implicit sorry, never learned it yet.
    Might wanna double check everything, did it while watching TV/eating breakfast.




    Big images, sorry... My iPhone is ridiculous.

    step by step? whoops. i mean... i kinda did it step by step. and i wrote more there than i normally would.
    summary of 'methods' used in each one.
    15 - chain rule and power rule
    16 - same
    17 - chain rule
    18 - chain rule and power rule
    19 - implicit differentiation rule? is that a rule even?
    20 - same
    21 - same, just twice.
    22 - implicit differentiation then just subbed x and y values in.
    23 - same, but then used point slope form of a line.
    24 - power rule and product rule (could have used the division rule, whatever that is called)
    25 - same + chain rule
    26 - expansion and power rule

    Learn a program like scilab so you can always check the plotted answer. This way you can visualize it a bit. (imo better than just reading the answer).

    and i just realized i posted one of them twice. i missed the third page!

    oh look. i made a mistake on 17. 9*6 is 54, not 63. @Sin; your 15 is missing a -1/2 exponent on the middle term.

    thats all i noticed though. meh. i probably did the implicit wrong. i cant recall the last time i did actual derivs and integrals. technology has made me lazy.

    Hello Mates, I got a 92 on my first test thanks to y'all for clearing it all up for me!

    I just posted 3 new pages of my review, if someone could help me understand the way @Sin and @Turpinator did, that be great!

    Thank you. Hope to get it by tonight so I can pull an all nighter.
