- 4.3-10arrow_forward8. Calculate the Fourier series f(t) (given in Question 2) as a half-range function showing the first three terms. DO IT ACCORDING TO THE FOLLOWING STEPS: 8.1, 8.2 AND 8.3. 8.1 All the integral expressions for the Fourier coefficients you will be calculating (ao, an, bn). 8.2 The complete DI diagram(s) you will be using to calculate the above integral(s). 8.3 Then determine the simplified Fourier Series f(t) up to and including the third term.arrow_forwardQuestion 7arrow_forward
- 2. ASSIGNMENT Economic data is quite variable and very complicated, making it difficult to model. A rough approximation of the U.S. Gross Domestic Product (GDP) growth rate is shown by the graph 10 20 given by G(t) = 5 cos (4 + 5) +2, where t is in years from 0 to 25 (inclusive) and where t = 0 represents January 1, 1985. If the GDP growth rate is positive, the economy is said to be expanding and if it is negative, the economy is said to be contracting. A recession occurs when the GDP growth rate is negative. (1) Using the given model, determine the intervals of time the U.S. economy was in a recession. Write up your response within economic terms. (2) Find the critical numbers of G and explain what these numbers mean in economic terms. (3) Determine the intervals on which G'(t) > 0 and on which intervals G'(t) < 0. Explain what each of these intervals means within economic terms. (4) Find all of the local extrema of G, explaining what these values mean within economic terms. (5) Find…arrow_forwardSketch the graph of a function that satisfies all of the given conditions. problem # 57arrow_forward4.
