Spaghetti Trigonometry – Extension

This is a direction I found myself going when some students had finished this activity.

– What would the graph of y = sin (2x) look like?
– y = 2 sin (x)?
– y = sin (x+2)
– y = sin (x) + 2?

Why?

What does this tell you about?
– f(ax)
– a.f(x)
– f(x+a)
– f(x) + a

Next lesson we are going to bring together everything we know about linear, polynomial and trigonometric functions and make some amazing graphical patterns using http://www.desmos.com/calculator. I hope to post the best ones here.
