When calculus was invented‚ has always been a question in Math. The first signs of calculus were done by Greek mathematicians. Zeno of Elea of about 450 B.C. gave a number of problems which were based on the infinite. His argument was that motion is impossible. Other Greek mathematicians that contributed to the method of exhaustion are Leucippus‚ Democritus and Antiphon. The method of exhaustion is so called because one thinks of the areas measured expanding so that they account for more and more

2. CheckPoint Cost‚ Volume‚ and Profit Questions 7. How should mixed costs be classified in CVP analysis? What approach is used to effect the appropriate classification? The mixed costs must be broken down into fixed and variable elements. After that is done then one needs to gather the information of the activity of the variable element in order to show the high end use and the low end use. It is important to separate these costs because the fixed cost will never change but the variable cost

Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because

Taviana Webb Period 1 Culminating Task #1 Rotation: The rotation transformation is where you turn a figure about a given point. The point that the obtated about can be inside the figure or anywhere outside it. The amount of rotation is called the angle of rotation and is measured in degrees. You can rotate shapes or figures on a coordinate grid. Each quadrant differs in degrees when working with rotations. Going clockwise the first quadrant is 90 degrees ‚ the second quadrant is 180 degrees
