Quick Methods Q's

(1) The slope of a childs slide is given by dy/dx = 9/32(x^2-4x) for x (some weird e shape) [0,4], where the origin is taken to be at ground level beaneath the higherst point of the slide, which is 3m above the ground. all units are in metres.

find the equaion of the curve, which describes the slide

[Collin Li]

Not sure what the initial condition is. I can't interpret the question very well!

Simply anti-differentiate to obtain:

for

Substitute in the initial condition to solve for .

[Glockmeister]

I think the initial condition is y=3, x = 0,

From this line:

origin is taken to be at ground level beneath the highest point of the slide, which is 3m above the ground

NB: I've fixed the spelling mistakes.

[Collin Li]

To me, it sounds like it's saying that the origin is the ground level (which for some reason, it tells us is beneath the highest point of the slide that is 3 metres above the ground).

Or does it mean to say the origin is at the ground level (which is 3 metres above the ground)? That's a contradiction.

[Mao]

its a slide, so should start high...

i think he misused the first "ground"
