trouble with question (1 Viewer)

Hey guys, cant do this question.....

"Sketch the curve y=1 - sin2x for 0≤x≤180º"

Well this is what I think i know so far........ the 1 means the curve will go through 1 in the y axis, and bend somehow to 2?

Please guys, I have no idea.

Please guys, I have no idea.

the 2x squashes the sin graph by a factor of 2
the minus sign flips the graph in the x axis.
the 1 shifts the graph up one.
substitute in pts if ur really having trouble

here is to represent what shafqat said graphically...

What program did you get that from haboozin?

Mathematica is good, too.

Sorry, I meant Graphmatica there. You can download it here: http://www.graphmatica.com/

I suggest you do! It's a lovely programme, and free.

yeah graphmatica is nice although graph v3.0 from download.com beats it.

Care to validate your statement with some justification?
