It started out as a snowy week - it snowed for an entire dayl Then it warmed up for a day, snowed for two days straight, and has been dry since. An equatión that equation: Scos(2t) 0sts S(t) = 57 23.92. A graph of the snowfall rate is shown below Note 4. S(1)
Riemann Sum
Riemann Sums is a special type of approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids and is used in integrals when finite sums are involved. Figuring out the area of a curve is complex hence this method makes it simple. Usually, we take the help of different integration methods for this purpose. This is one of the major parts of integral calculus.
Riemann Integral
Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.
a) using the graph, on what days is the snow on the ground increasing?Decreasing? How do you know from the graph? ( Express in interval notation)
b) set up and evaluate a definite
c) what does the definite integral represent in the context of the problem?
d) if there was 6 inches of snow on the ground to begin, how much snow is there after 4 days?
The given graph is shown below.
From the graph, it can be seen that in the interval is decreasing , in is increasing and it is decreasing again. For . It implies that between ay 0 and daythe snowfall rate is decreasing and from day to day 3, this rate is increasing. From day 3, it is again decreasing and from day 4 and onwards, this rate becomes zero.
The given model representing the snowfall rate is given by
