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

4. Couldn't do the ones with implicit sorry, never learned it yet.

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

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

8. lol 16 yr old maths, ohh the days of ease

9. 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.

11. Guys I honestly appreciate the help, and @turpinator can you please post the third page ? I have my exam on Monday .

15. 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.
