Can you work out the equations of the trig graphs I used to make my pattern?
Can you sketch these difficult curves, which have uses in
Can you make a curve to match my friend's requirements?
Plot the graph of x^y = y^x in the first quadrant and explain its
10 graphs of experimental data are given. Can you use a spreadsheet to find algebraic graphs which match them closely, and thus discover the formulae most likely to govern the underlying processes?
Draw the graph of a continuous increasing function in the first
quadrant and horizontal and vertical lines through two points. The
areas in your sketch lead to a useful formula for finding
In this trail, a new type of NRICH resource, learn about
transformations of graphs. Given patterns made from families of
graphs find all the equations in the family.
Sketch the graph of $xy(x^2 - y^2) = x^2 + y^2$ consisting of four curves and a single point at the origin. Convert to polar form. Describe the symmetries of the graph.
Investigate the family of graphs given by the equation x^3+y^3=3axy
for different values of the constant a.
Sketch the members of the family of graphs given by y =
a^3/(x^2+a^2) for a=1, 2 and 3.
Can you massage the parameters of these curves to make them match as closely as possible?
Which curve is which, and how would you plan a route to pass between them?
Make a catalogue of curves with various properties.
This task depends on learners sharing reasoning, listening to
opinions, reflecting and pulling ideas together.
Can you fit a cubic equation to this graph?
Sketch the graphs for this implicitly defined family of functions.
What biological growth processes can you fit to these graphs?
Compares the size of functions f(n) for large values of n.
In this 'mesh' of sine graphs, one of the graphs is the graph of
the sine function. Find the equations of the other graphs to
reproduce the pattern.
Investigate the graphs of y = [1 + (x - t)^2][1 + (x + t^)2] as the
parameter t varies.
This function involves absolute values. To find the slope on the
slide use different equations to define the function in different
parts of its domain.
This polar equation is a quadratic. Plot the graph given by each
factor to draw the flower.
