Note that the negative signs indicate direction, and follow from the position of the vectors with respect to the chosen coordinate system, i.e. the x-y plane, with conventional directions …

Since this system involves the equation of a circle (e.g #x^2 + y^2 = 65#), the solution set will be of the form # (a, b); (b, a)#.

Vestigial organs are supposed to be relicts of a past function in a more primate organism. The appendix was once thought to have no useful function in human beings. It is now known that a …

Solution: d/dx (e^x sqrtx) = e^x sqrtx + (e^x)/ (2sqrtx) Explanation: When differentiating a function which in and of itself is the product of two functions, it sometimes behooves us to use the …

The gradient of a scalar function, shows the direction in which the function increases at any point # {x,y}#. In the two dimensional case #vec r = {x,y}# so #1/abs (vec r) = 1/sqrt (x^2+y^2)# and …
