Question: Find the tangent line to the graphx2(x2+y2)=y2at the point(22,22). Tangent Line: To find the tangent line the first thing we must determine is the slope of the line. To do this we have to calculate the derivative of the functio...
Find the point on the graph of y=x2 where the curve has slope m=23. Slope at a Point: In this problem, we are asked to find a point on a graph at a specified slope. The slope at any point, can be found by using the derivative of the graphed equation. Once the deriv...

Which of the following describes the graph of the equation (x+y)2=x2+y2?A.the empty setB.one pointC.two linesD.a circleE.the entire plane 答案 CExpanding the left side, we have x2+2xy+y2=x2+y2⇒2xy=0⇒xy=0⇒x=0 or y=0.Thus there are two lines described in this gr...
Given the equation of an ellipse: 4x^2 + 25y^2 = 100 Use the integration process to find the total area enclosed by that ellipse. Use Green's theorem to evaluate the line integral over C of 2xy dx + (x^2 + y...
我们定义:一个整数能表示成a2+b2(a,b是整数)的形式,则称这个数为“完美数”.例如,5是“完美数”.理由:因为5=22+12.再如,M=x2+2xy+2y2=(x+y)2+y2(x,y是整数),所以M也是“完美数”.解决问题:(1)请你再写一个小于10的“完美数” 4;并判断40是否为“完美...
例如,把二次三项式x2-2x+3进行配方解:x2-2x+3=x2-2x+1+2=(x2-2x+1)+2=(x-1)2+2我们定义:一个整数能表示成a2+b2(a,b是整数)的形式,则称这个数为“完美数”.例如,5是“完美数”,理由:因为5=22+12,再如,M=x2+2xy+2y2=(x+y)2+y2,(x,y是整数...
