how do i estimate the area under the graph of f(x) = 2 cos(x) from x=0 to x= T / 2 using four approximate rectangles and right endpoints . how would i round it to 4 decimal places? And how would the graph with the shaded rectangles look like ? would it be an overestimate? the last person gave me an AI answer but i need a written paper to understand. please show me what the graph exactly looks like. thank you so much

continuing off of that question: 4. In the next two parts of the question, you will calculate the approximate area under the curve using the right end-points of the sub-intervals. Complete the following table (for the second column, you should only have to do one calculation from scratch, since you have already calculated three of the numbers earlier in the question). x1 : f (x1) : x2 : f (x2) : x3 : f (x3) : x4 : f (x4) : 5. Now calculate the approximate area under the curve using the formula Approximate area under curve : 6.In the next two parts of the question, you will calculate the approximate area under the curve using the mid-points of the sub-intervals.

An experimental self-driving car is observed as it moves back an forth on a straight stretch of road. The car's velocity ( measured in meters per second) is a function of time (measured in seconds). The velocity is shown in the graph below. Positive velocities mean the car is moving toward the east and negative velocities mean its motion is toward the west. Using the values given below for the labeled areas in the graph, determine how far east of its starting position the car was at the end of t = 10 seconds. A = 2 B = 8 C = 15 Velocity in meters per second Time t = 10 В seconds
