Could you actually just format it so that it’s readable?

#

Ok first question is the area bounded by the curves y=sin(x) and y=sin(2x) in [0,Ο€]

#

I’m not going to take the effort to read the rest, please make your questions readable

I think

#

Ok @cyan loom do you have any idea how to start?

Start by graphing the curves with a rough sketch, and then determining which function is on top vs. bottom

and graphing

harsh island
#

Well a rough sketch works ig

#

You could also notice that both functions have the same starting point but sin(2x) grows faster at the start, so until some R ∈ [0,Ο€], sin(2x) > sin(x)

#

Then you can find that R
