I know you guys can help me! Not to blabber on, here's my situation: When talking about using definite integration to find areas, I'm very familiar with how to find the area under a curve (i.e. the area between the curve and the x-axis) the area between two curves a volume of revolution about one of the axes And I understand most of these operations can be reduced to a simple formula or algorithm for solving the problem SO my question is as follows: [color=#0000BF]Is it possible to find an area between a curve and the y-axis? [/color][color=#000000]And if yes, what is the formula/algorithm to find the area?[/color] [color=#0000BF]AND how to find the area bounded by a curve and lines parallel to the axes?[/color] [color=#000000]Again, if there's a simple formula/algorithm for this, that would be greatly appreciated.[/color] [color=#000000]I don't doubt questions like these are a piece of cake for you guys, so sorry for bothering you with them, but I just can't get to grips with them, and I would really appreciate any help on the topic! [/color] [color=#00BF00]Thanks beforehand![/color][color=#000000] Cheers! Phil[/color]

Yes , it is the same for that with the x-axis but this has only meaning if the function is one-to-one .
