Approximate the net signed area under the graph of y=x-1 curve on [0,2], using rectangles with n=4 and n38 when taking the right end points as your sampling points (sampling points are the points where you are measuring the heights of the rectangles). This is the beginning of the section 5.3 we have started. Have a picture of the graph and all the spu ific values. For example, for n=4, you interval of [0,2] of f(x) will have f(1/2)times delta x +f(1)*delta x+ f(3/2)*delta x+f(2)*delta x=the area of A1+A2+A3+A4=?? Delta x is, of course, the width of our rectangles. It is equal to the distance between the two sampling points! Then you will divide into n=8 subintervals..You will need deltax= (2-0)/8=1/4, and you will need f(1/4)*deltax+f(2/4)*deltax+. =you will have 8 rectangles. Area= (approximately) A1+A2+A3+A4+A5+A6+A7+A8 Submit your approximation here as your notes: Beginning of 5.3 Area under the graph = 04/30/20: Notes you need to have This announcement is closed for comments Search entries or author Unread %23 hp

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
