Right now I am extremely behind in class still stuck on the end of Circle Geometry and my class is almost done with perms and coms. I'm afraid by the time I reach the area they would have already moved onto some new topic so I was wondering how hard is perms and coms? Is the topic simple enough...
What is the equation of the normal to x=2t, y = t^2 at the point t=3. Not sure where to begin with this question. I know how to find the equation of the normal if I'm given a curve though like y=4x - x^2.
^title, so after I tried writing a few practice creative writing pieces, I found that I have an image of the scenary in my head but lack the vocabulary to describe the image. I find it difficult to find the right word for certain objects, for example names of specific hat types, describing a...
I have an upcoming 3U test on trig and I'm not too sure which of the 3 cos2x expansions to use and when.
e.g cos2x = cos^2x - sin^2x, 1-2sin^2x, 2cos^2x - 1
Can someone explain in what situation would I use one expansion over the other?
Example question: 1+cos(180degree + 2x)
How come to...
This might be a stupid question but can anyone explain what the letters represent for the formulas used in the moving about topic? I can't seem to remember them or don't know what they represent.
eg: Ft = mv - mu, W = Fs, V^2 = u^2 + 2as, p=mv, s=ut + 1/2 at^2
