Trigonometric Edition Part 2Can you find trig graphs to satisfy a variety of conditions?http://nrich.maths.org/11647Mon, 01 Jun 2015 00:00:01 +0100Two-way FunctionsThis gives you an opportunity to explore roots and asymptotes of functions, both by identifying properties that functions have in common and also by trying to find functions that have particular properties. You may like to use the list of functions in the Hint, which includes enough functions to complete the table plus some extras.You might like to work on this problem in a pair or small group,
or to compare your table to someone else's to see where you have used the same functions and where not.http://nrich.maths.org/11301Sat, 01 Nov 2014 00:00:01 +0000Picture the Process IHow does the temperature of a cup of tea behave over time? What is the radius of a spherical balloon as it is inflated? What is the distance fallen by a parachutist after jumping out of a plane? After sketching graphs for these and other real-world processes, you are offered a selection of equations to match to these graphs and processes.http://nrich.maths.org/11299Sat, 01 Nov 2014 00:00:01 +0000Which Quadratic?In this activity you will need to work in a group to connect different representations of quadratics.http://nrich.maths.org/11266Mon, 01 Sep 2014 00:00:01 +0100Giants Posterhttp://nrich.maths.org/11227Mon, 01 Sep 2014 00:00:01 +0100Mega Quadratic EquationsAlison to turn into STAGE 5 to go with Power Quady 1838http://nrich.maths.org/11009Wed, 01 Dec 1999 00:00:01 +0000Nine EigenExplore how matrices can fix vectors and vector directions.http://nrich.maths.org/6877Tue, 01 Feb 2011 00:00:01 +0000Name That GraphHow can you work out the equation of a parabola just by looking at key features of its graph?http://nrich.maths.org/11922Wed, 01 Dec 1999 00:00:01 +0000Inspecting IdentitiesUsing trig identities to help sketch graphs of functionshttp://nrich.maths.org/12146Thu, 01 Jan 2015 00:00:01 +0000$t$ for tanCan you find a geometric proof for some $\tan\theta$ trig identities?http://nrich.maths.org/12148Thu, 01 Jan 2015 00:00:01 +0000
