Show that the value of ∫ (from 0 to 1) \[\sqrt{x+8}dx\] lies between 2\[\sqrt{2}\] amd 3.

2sqrt2 and 3. sorry idk why it is formatting the text like that.

so i take it instead of doing the integral.. they want the proof method.... i can try and sum it up

the theorems? like if it's even or odd?

so we know that this shaded area is almost a rectangle... and that area is BH but the B=1 so its just the H that matters.... which is between sqrt of 8 and 3......

that last part i meant sqrt(8) and 3 the area is between one of those 2 because this shape has a little slop on the top so it is just a little bigger then the sqrt(8) but also less then 3.... does this make sense? dw:1359001866185:dw

yea i see that from f(0) and f(1), the values are between 2.8 and 3, but i have trouble putting it into integral form? :(

putting it in integral form? you mean like actually solving it? i can show you how

well i think that it's asking me to write a proof or to explain it in calculus... i kinda forgot the word for it lol

i think it's like boundaries?

Goten77Best ResponseYou've already chosen the best response.0
yes it has boundaries and limits to what its area is restricted to

swin2013Best ResponseYou've already chosen the best response.0
i think it's asking me to write the boundaries in integral form.. like 2.8 < integral from 0, 1... < 3. i don't know where to start lol!

aah... proofs are annoying... but as long as it makes sense its ok... if u have other "real" problems ied do those 1st... generally proofs are just long explanations .... and by real problems i mean were you can do work and get a answer.. proofs are just explaining calculus to some1 who hasnt taken it... and thats really hard... but eh i think u get it and thats all that matters

yea lol! i understand it, but i have trouble putting it into a "calculus sentence" or whatever they call it lol. i understand the area is between the 2.8 and 3 but i'm not sure how to translate it lol
