Please share your answer for q11 here

 

[Mr Hippopotamus]

For the last one, did you you guys shade the top half of the circle?

I guessed...and I shaded everything BUT the circle....

Same

 

[NFmusic1995]

you dont shade the circle

you sub in (0,0), and then yea, you find out its true. so shade the top right excluding the circle

 

[churnitout]

what was ur answer for the limits q?

 

[Jassinta]

I got 4 for the limits aswell, so hopefully it's correct, and I gave up and shaded everything above 4 on the y axis... Which I'm 98% sure is completely wrong

why did you shade only the top right excluding? The region is anything outside the circle in all sectors.
I think you needed to draw the whole circle

I just double checked on wolfram, and that is the case

Me too but... will the pencil show up?

Me too but... will the pencil show up?

I used a black felt tip pen for all the diagrams :L

 

[hjed]

4

wolfram says 3... not sure I got that right (right method, but I swear my answer was a multiple of 2)

I drew the circle about 4 times because it looked like an egg

 

[Recondit]

isn't limits 3?

 

[Randox]

Same wtf. I think i made a stupid mistake and put 4. just had a look...looks like it was 3.

 

[Randox]

isn't limits 3?

yeah it was.

 

[Shazer2]

what was ur answer for the limits q?

 

[churnitout]

shouldn't it be 1/2?...divide by highest power then sub 2

 

[LittlerCandy]

Well this is what I got, not sure if they're correct but.

(a) I hate significant figures and put 1.1 -_-

(b) 3

(c) (8cosx)(sinx -1)^7

(d) 2xe^x + (x^2)(e^x)

(e) 1/4[e^(4x+1)] + C

(f) 1/3(ln2)

(g) Centre (2,3) r=2 fucked up the region shading :/

Hopeful 13/15

 

[LittlerCandy]

shouldn't it be 1/2?...divide by highest power then sub 2

You only divide by highest power when the limit is approaching infinity or zero.

 

[nailafun]

I didn't even shade, as it only said "sketch" .....

 

[Jassinta]

Well this is what I got, not sure if they're correct but.

(a) I hate significant figures and put 1.1 -_-

1.10, close but no mark for ju D: The 0 counts as a significant figure if it's the last or middle figure

(b) 3

Seems to be correct according to Wolfram

(c) (8cosx)(sinx -1)^7

This better be right because I got the same

(d) 2xe^x + (x^2)(e^x)

Same as me again, let's hope we're right

(e) 1/4[e^(4x+1)] + C

(f) 1/3(ln2)

(g) Centre (2,3) r=2 fucked up the region shading :/

Hopeful 13/15

Not sure about some of them, but that's my input
