Hey no worries, Mark44, beside I found my version of the solution completely out of luck just bored and messing around with my calculator :P You're version of the sum of two terms is just as valid isn't it?

It only works with odd numbers (√1.5 + √3.5)2 + (√1.5 + √3.5)2 = (√3 + √7)2 The left side is 2 * 9.58 = 19.16. The right side is 19.16(√44.5 + √6.5)2 + (√44.5 + √6.5)2 = (√89 + √13)2 The left side is 2 * 85.014 = 170.029. The right side is 170.029 yesh?

3[√3+√5+√7]^2 3[√(1.5)+√(2.5)+√(3.5)]^2 + 3[√(1.5)+√(2.5)+√(3.5)]^2 up in the middle of the night doing this.. so I may have broken a million rules getting to this point :blushing: You Might want to double check but they seem equivalent :devil:

Aha! Office_Shredder, I see what you mean! you're right, I was jumbling things up there a little bit! Thanks for clearing that up, homie!

Thanks! okay that makes a lot of sense actually :D SO its one or the other, right? How do I prove whether its constantly increasing or decreasing using derivatives? cuz normally I would equate the derivative to zero.. take the values that gives me for x.. and consider those 'significant...

Homework Statement hey Forum! I had a question here I'm struggling with and was wondering if someone could take a look. its Dealing with calculus, specifically derivatives and behaviors of the graph: http://i41.tinypic.com/mc6opj.jpg I just started and part a) already has me stumped D...

here are sketches for my graphs: how do they look? thanks again!

Hey forum, I know this is an easy one, but it's been a while for me :P thanks for your help! Homework Statement Given the following graph of h(x) a) The intervals where h(x) is increasing and decreasing b) The local maximum and minimum points of h(x) c) The intervals where h(x) is...

yes, so I did it right then?

yes thank you SammyS :) so far I'm at caught up with you to this point so I'm thinking that g'(x) = 11/(x^2+8x+16 is a better answer than g’(x) =2(x + 4)^(-1) – (2x – 3)(x + 4)^(-2) yes? Also any thoughts on my second derivative answer?g’’(x) = -2(x + 4)^(-2) – 2(x + 4)^(-2) +(–4x + 6)(x +...

oh wow okay.. I just worked my answer of g’(x) =2(x + 4)^(-1) – (2x – 3)(x + 4)^(-2) through and got the same answer of g'(x) = 11/(x^2+8x+16) I see what you mean! so is the second answer (in red) better than my other answer? obviously they are equivalent but you can see I got mine from using...

What do u and v represent?

where does the 11 come from?

Homework Statement Hey forum, hope everyone is having a good day! If someone could check this question out for me that'd be great! Determine the first and second derivative: g(x) = (2x - 3)/(x + 4) The Attempt at a Solution g(x) = (2x – 3)(x + 4)^(-1) g’(x) = (2x – 3)’(x +...

:D ohhhh yes I do.. damn that seemed really obvious >.> so we are using: the derivative of the function f(x)=a^g(x), where 'a' is a positive constant, is given by f'(x)=a^g(x) lna g'(x) and for the question h(x) = 3e^sin(x + 2) lne is established, however, simplified out later because...
