Excuse but do these notes cover the new 2010 syllabus?

LOOOOOOOOOOOOOOOOOL I hate drawing graphs TBH I suck at drawing :( Teacher tells me off when I don't draw graphs and im like IT DON'T TELL ME TO DRAW GRAPHS PLEASE... haven't met alot of people that actually use the word "doomed" like myself

Yea I know I want to learn the algebraically method that always works, because usually they aren't symmetrical and I don't want to repeat the same mistake.

My friend did it he basically just integrated y^2=x^4 and multiplied it by 2.... which makes sense when you draw the graph but like... :(

Don't you have to combine the equations together??

YES I GOT THAT TOOO But the answer says 2PI/3 units^3 and I got 33Pi/5 Units^3

I keep getting the wrong answer tho. My algebra is clearly wrong can you perhaps show me?

Find the volume of the solid of revolution formed if the area enclosed between the curves y=x^2 and y=(x-2)^2 is rotated about the x-axis.

I have this assignment on how I need to find practical applications on trigonometric functions, and I found Aerospace engineering to be the most easiest since there are more sources on it on google. Now I have found formulas that have trig in them but my assignment says I need to show how to...

Thanks for the quick reply

Use the four standard forms to find the equation of the parabola with vertex at the origin and with the follow properties: a) axis vertical, passing through (4,1) b) axis horizontal, passing through (2,-2) I don't understand what it means by axis vertical/horizontal, if anybody can clarify...

do you know how i can find how far the projectile will travel in the first 4 seconds?

I thought when you make the velocity = 0 thats when it rests.

A projectile is fired into the air and its height in metres is given by h = 40t − 5t^2 + 4, where t is in seconds. (d) What is the maximum height

Oh thanks i got up to finding dx/dt i didn't consider having to use another formula to find the answer.

Here is the question: If the volume of a cube is increasing at the rate of 23mm^3/second find the increase in its surface area when its side is 140 mm.

To win a trifecta in a race, a person has to pick the horses that come first, second and third in the race. For a certain race, Marie wishes to bet on every combination possible to win the trifecta. If there are 12 horses in the race, how many combinations will she bet on? PS: Stuck on this...

Oh sorry its (1/8)x^3

The region in the first quadrant bounded by the graphs of f(x)=(1/8)x^3 and g(x)=2x is rotated about the y axis. Find the volume of the solid formed.
