This is taken from Wikipedia: Many of the methods for calculating square roots of a positive real number S require an initial seed value. If the initial value is too far from the actual square root, the calculation will be slowed down. It is therefore useful to have a rough estimate, which...

Another way of thinking about it?? \sqrt{b^{2}-4ac} \sqrt{(2f)^{2}-4(2d+1)(2(2j+1))} 2f is even, so (2f)2 is even and 8(2d+1)(2j+1) is even x (odd x odd). (odd x odd) is odd so then even x odd = even \sqrt{even number -even number} even number - even number = even. = 2m so...

Homework Statement I have to show a proof that if a is odd, b is even, and c is even but not divisible by 4. a,b,c are int coefficients ax2 + bx + c = 0 has no rational solutions Homework Equations all letters here are integers. So i have, a = 2d + 1 b = 2f c = 2g, but c...

im in a multivariable calculus class right now, and the point given was (2,3,-1) what i did was take the partials w/ respect to x y and z. then i plugged in the values at that point. then i plugged that into the equation fx(x-x0)+fy(y-y0)+fz(z-z0)= 0 i ended up getting 11x-2y+13z...

Im trying to check my answers to a problem, and in the past I've used a 3d grapher to graph functions like f(x,y) = whatever. but now i need to find a tangent plane to a surface at a point. the surface is: x2y+y2z-z2x=1but i don't know how to go about graphing something expressed that...
