Hello Mates, can someone please help me with these last few questions of my review with step by step please?

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

all of them? ill take a look at them in 45 mins.

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.

with step by step please?

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

lol 16 yr old maths, ohh the days of ease

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).

Smart of you to put your own name in the forumulas. Now we can see turpinater just copied it all!

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.

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

ya know… i would, but i uploaded and scanned it at work. ill redo that in a bit.

here is the implicit come on turp, this took 5 mins ( 2 mins to do the entire sheet and 3 mins to take the photo and upload)

Damn it turp, mr plageurizer!

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.

better resolution pics next time pl0x.
