Hi people, I have two questions and help on any of them would be greatly appreciated. 1. My first question is how would i find the point(s) where the two equations intersect? eg. 4*(x-1)^2+(y-2)^2 = 5; x^2+4*y^2 = 1; 2. My second question is how do i find the turning points of a function? eg. x*cos(x^2)/(1+x^2) Again any help is really appreciated. Thanks in advance.

Hi again people, I have just another little quick question and that is if I graph two polynomial functions on an interval is there a way to find where the two polynomial intersect each other? Can it be done without graphing? Again I need accuracy to 3 decimal places. Thanks again.

Hi people, I am actually taking a maple practice test and am wondering how would I go about doing a higher order derivative of this function. f(x) = sin(x^2/(x^10+2))*e^(2*x) I would like to find the 8th deriavtive at x = 0 to 3 decimal places. The answer is 112.000 but i would still like to know how to solve it as in the real test there will be one just like it. If someone could give the algorithm that i would put it in that would be great. Used the help feature but it was not all that helpful. Thanks in advance. Tabish
