It is worth stressing that the reason dots of a group can be discrete but a continuous shape is implied is because the dots trigger a shape function. A function such as y = ax2 + bx + c is continuous. This is useful in nature, since an extended object such as a log...
The vertex formula helps to find thevertexcoordinates of a parabola. The standard form of a parabola is y = ax2+ bx + c. The vertex form of the parabola y = a(x - h)2+ k. There are two ways in which we can determine the vertex(h, k). They are: (h, k) = (-b/2a, -...
Form the differential equations by eliminating the arbitrary constants... 01:34 What is the differential equation of the curve y=ax^(2)+bx ? 05:07 y= (c1+c(2)x)e^(x) 01:42 y = c(1) e^(2x) +c(2)e^(-2x) 02:22 If y= a cos 2x + b sin 2x , then 02:44 y^(2)=...
The graph of a quadratic function is a parabola. If the parabola opens upwards, that is, if the leading coefficient is positive, then the minimum value of the function will be at the vertex, which may be found from the general form {eq}y=ax^2+bx+c {/eq} using {eq}x...
