Math Portfolio HL- Type 1 INVESTIGATINGRATIOS OF AREAS AND VOLUMES The purpose of this portfolio is to investigate the ratios of areas and volumes when a function y= xn is graphed between two arbitrary parameters x=a and x=b such that a‹b. Task 1 The general formula to find area A is [pic] The general formula to find area B is [pic] Therefore‚ the ratio of Area A to Area B is- = [pic] ÷ [pic] = [pic] × [pic] = n : 1 n:1 is the general conjecture formed. The given

Calculus of one variable Let y = axb‚ where a and b are numbers‚ with b different from zero. The derivative of y with respect to x is dy/dx = abxb-1 Examples: y = 2x7‚ dy/dx = 2*7x7-1 = 14x6 y = 5x0.3‚ dy/dx = 5*0.3*x0.3-1 = 1.5x-0.7 Exercises: Calculate dy/dx a) y= 3x2 b) y = 12x0

neighbors. I like cars because it’s been my interest since I was very small and I still love them. I love movies because it’s fun and relaxing to watch and I like playing outside because it gives me great energy. I pretty much do anything I can during free time. One of my hobbies is learning and knowing a lot about cars because it’s very interesting to me. In school I don’t do much but I might start to do something that is interesting and helpful for my future. Recently I have no job but might get one during

Math 116 - Chapter 6 review Name___________________________________ Provide an appropriate response. 1) Two random variables are normally distributed with the same mean. One has a standard deviation of 10 while the other has a standard deviation of 15. How will the graphs of the two variables differ and how will they be alike? 2) Which is larger‚ the area under the standard normal curve between -1 and 1‚ or the area under the standard normal curve between 0 and 2? Explain your reasoning

Jesus Toro-Sanchez 03/13/2013 Math 60 Chapter 4 Writing Assignment 1) Explain how to plot a point in the rectangular coordinate system. Give example with your explanation. a. In order to plot a point in the coordinate system‚ you will need the X coordinate as well as the Y coordinate. For example‚ the point (3‚5) can be plotted be going right on the X axis 3 points‚ and going up on the Y axis 5 points. Remember the opposite goes for negatives. 2) How many Points are needed to graph
