check out #24, im having problems evaluating the ln(1-a) part cause i know that i cant do ln(0) correct? THANKS

its been some time since i last did a completing the square problem and i need help with it. complete the square: 16x^(2)+16x+5 thanks

a farmer plans to fence a rectangular pasture adjacent to a river. the pasture must contain 180,000 square meters in order to provide enough grass for the herd. what dimensions would require the east amount of fencing if no fencing is needed along the river? since, i am given 180,000 SQUARE...

can someone explain this formula and what the values mean for linear approximation. f(x) (swiggly)= f(Xo) + f'(Xo)(X-Xo) i dont seem to understand the concept or what i should put in the formula. thanks

thanks. i wasnt a 100 percent sure on what to do with the constant but now i do. thanks

check the graph of 1/x and you can see that there can not be a two sided limit as x approaches zero because the graph of the function are going to opposite directions. therefore it does not exist. hope this helps. it also helps to know how the graphs look like

hello all, im having problems with taking the derivitive of constants and implicit differentiation whats d/dx of pi(sinx)? what do i do with the pi? can i do implicit differentiation or is that only with "y"s?? thanks

can you elaborate on that? i wanted to know how to rewrite the problem so i can use L'Hopital. my friend calls it hospital because it sounds funnier. :haha::haha::haha:

help with: lim [cos(2/x)]^(x squared) x-> +infinity and lim (2-x) ^tan [(pi/2)x] x-> 1 thanks

thank you.

hi, i need help with linear approximatons. use the differential dy to approximate (delt)y when x changes as indicated: y = sqrt(3x-2); from x = 2 to x= 2.03 (when doing a problem, how do i know when to use the formula or solve for the tanget line.) thanks in advance
