(c) is left for you to then.This is the question in my book and I can't seem to get an answer:
14 (a) For the function: the area under the curve from x = 0 to 1 and the x axis, can be found with the equation . What is the equation for the area under the curve from y = 0 to 1 and the y axis? I got . Is this right? Mr F says: Yes. And how you got this answer is probably the way you need to get the answers to the next two questions.
It then says
(b) With the same function (), the equation for x = 0 to 2 and the x axis can be found with: . What is the equation for the area unde the curve from y = 0 to 2 and the y axis? I don't know what to do here
Mr F says: The area of the rectangle is . Then the required area is
And finally.. (however, if we can get the right answer to (b) i'm sure (c) will be done too)
(c) For the same function () the equation for x = 2 to 3 and the x axis is . What would the equation be for the area under the curve for y = 2 to 3 and the y axis?
