Save guides, add subjects and pick up where you left off with your BBC account. All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic ...

Simultaneous equations where one of the graphs is quadratic and the other is a straight line can also be solved by reading the points of intersection. Example The graph of \(y = x^{2} – x – 2 ...

In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph of a non-linear function is a curved line. A curved line is a line whose direction ...

The graphs for the pair of simultaneous equations intersect at \(\left(\dfrac{43}{13},\dfrac{85}{26}\right)\). Solving simultaneous equations with an unknown coefficient, \(k\) Questions that include ...

This letter presents a simple graphical criterion to obtain all common quadratic Lyapunov functions for nonlinear systems contained in the convex-hull of a set of second-order linear time-invariant ...
