So what would happen if But if you wanted this total area, what you could do is take this blue area, which is positive, and then subtract this negative area, and so then you would get Find more Mathematics widgets in Wolfram|Alpha. to polar coordinates. So I know what you're thinking, you're like okay well that The error comes from the inaccuracy of the calculator. :D, What does the area inside a polar graph represent (kind of like how Cartesian graphs can represent distance, amounts, etc.). And we know from our In most cases in calculus, theta is measured in radians, so that a full circle measures 2 pi, making the correct fraction theta/(2pi). So times theta over two pi would be the area of this sector right over here. And what I wanna do in Area between a curve and the x-axis: negative area. a circle, that's my best attempt at a circle, and it's of radius r and let me draw a sector of this circle. The rectangle area formula is also a piece of cake - it's simply the multiplication of the rectangle sides: Calculation of rectangle area is extremely useful in everyday situations: from building construction (estimating the tiles, decking, siding needed or finding the roof area) to decorating your flat (how much paint or wallpaper do I need?) I cannot find sal's lectures on polar cordinates and graphs. little sector is instead of my angle being theta I'm calling my angle d theta, this In this case the formula is, A = d c f (y) g(y) dy (2) (2) A = c d f ( y) g ( y) d y Direct link to dohafaris98's post How do I know exactly whi, Posted 6 years ago. So that is all going to get us to 30, and we are done, 45 minus 15. Then solve the definite integration and change the values to get the result. This process requires that you keep track of where each function has a greater value and perform the subtraction in the correct order (or use an absolute value). Direct link to Dhairya Varanava's post when we find area we are , Posted 10 years ago. I'll give you another And what would the integral from c to d of g of x dx represent?
