Thanks for replying :) I tried a histogram but then it just gave me counts... but since we can draw things by hand I've decided to make a scatterplot and just draw bars overtop since I can't seem to get the whole thing to work out

I'm trying to make a bar graph from data which were taken at irregular intervals over 100m. I want the x-axis to be scaled instead of showing each data point one after another. (i.e. I'm coming out with 1-4-5 when I want 1-----4-5). I hope this makes sense - I'm not sure of the proper...

In order to get an integral I need to find the difference between two functions, but I'm not sure how to deal with the absolute value... f(x) = \left|x-1-1\right| g(x) = x^2 + 2x g(x) - f(x) = (\left|x-1\right|-1) - (x^2 + 2x) =... I don't know if I can simplify it anymore... can I...

Oh right.. that makes sense! Thanks for taking the time to reply :)

Thanks, but we actually haven't covered the sub rule yet so I'm wondering if maybe there is a different way to get the answer? Updating because I found a similar question in my text... The text has a problem showing.. \int sin( \Pi x)dx = -(1/ \Pi )cos( \Pi x)dx So I take it if f(x)...

Hello :) I'm not sure how to deal with an integral of the form cos(2x), sin(2x), tan(3x), etc. Its the constant that is throwing me off - I know what the antideriv of cosx, sinx or tanx is. My text doesn't seem to explain what to do with the constant and I can't seem to find the info using a...
