Here is a lesson on Non-linear simultaneous equations. Three example problem pairs. Some questions. Something a bit more problem solve-y. 5 timed questions. Some exam questions. It’s quite basic, really.
I know I haven’t posted much recently.
I will try and post some more stuff.
There’s a big difference between stuff to make for myself and stuff to publish. I usually just find some questions and paste them in for myself. Writing the questions and getting this up to snuff for publishing took a good couple of hours, and it’s quite a basic lesson.
PS I recently subscribed to MathsPad and it’s really good.
