Not a whiz but got an A in Calc 1 and Calc II about 7 years ago....................of course I may be wrong about the 7 years thing.............I'm not real good with numbers. Let me know what you need.
Hope this helps,

It has been about that long for me too..I am trying to find the second derivative of sqrt(x +(sqrt x + (sqrt X))....who comes up with this!?
Thanks
Thanks
It's been a long time
It's been a long time
but I think it would be:
x + x^1/2 + x^1/2
1st derivative would be:
1 + 1/2x^-1/2 + 1/2x^-1/2
2nd derivative would be:
0 + -1/4x^-3/2 + -1/4x^-3/2
Or could be written as:
-1/2x^-3/2
Hopefully someone can verify (I would love to know if I got this right).

i don't think thats right. i got it down to 1/4(x+2(sqrtx)) all raised to the negative 1.5. thats the unsimplified answer... i think. im too lazy
Okay just one question, sqrt are all variables? or are you stating squared for instance square of t times x plus t squared ex.........see what I mean.
............The exponent becomes the co-efficient, then lessened by one and the variable becomes a one and then that equation, has the same principle applied. Right?
this one was a bitch to figure out

Calculus...grrr....
It is hard to type the question on the computer...I sadly do not think any of the responses are right. It is a multiple choice question with answers ranging from a to h... none of which correspond.....I guess I will pick C?!
Thanks for help...

btw, wasn't that math stuff made up from the same people and authors that made these coloring and activity books?

Money doesn't buy brains sadly...not that I don't have any..i consider myself smart....but there is no logical point for me to understand calculus principles. Especially questions that are meant to send you for a loop

That website is a calculator. Enter your function and then the f''(x) and that should give you the second derivative. I entered it but the answer didn't copy on here correctly so I am just giving you the website.

Multiple choice exam that you do at home...no amount of time or cheating is seeming to help find the answers:shrug:
