a. Sketch a phase portrait for the dynamical system
b. In his paper “On the Measurement of the
210 B.C.) uses the approximation
to estimate cos(30°). He does not explain how he arrived at these estimates. Explain how we can obtain these approximations from the dynamical system in part a. Hint:

- A two-stage gear train consists of four gears meshed together (Figure 10). The second and third gears are attached, so that they share the same angular velocity (2=4). Find a formula giving the angular velocity of the fourth gear, 2, in terms of 1 and the values of n1,n2,n3andn4.arrow_forward3.) Imagine a string that is fixed at both ends (for example, a guitar string). When plucked, the string forms a standing wave. The displacement, u(x, t), of the string varies with position x and time t. Suppose a,t) = 2sin(xx)sin() for 0 0. At a fixed point in time, the string forms a wave on 10, 11. Alternatively, if you focus on a point on the string (fix a value of r), that point oscillates up and down in time. a.) What is the period of the motion in time? За.) du 3b.) dt b.) Find the rate of change of the displacement with respect to time at a constant position (which is the vertical velocity of a point on the string.) 3c.) x = c.) At a fixed time, what point on the string is moving fastest? 3d.) t = d.) At a fixed position on the string, when is the string moving fastest? du 3e.) e.) Find the rate of change of displacement with respect to position at a constant time (which is the slope of the string.) 3f.) r =, f.) At a fixed time, where is the slope of the string the greatest?arrow_forwardThe number of hours of daylight each day for a particular city can be modeled using the sinusoidal function s(m)=5sin(2π/12m−π/2)+13 , where s is the number of hours of sunlight per day, and m represents the month of the year, with m=1 corresponding to January, m=2 corresponding to February, etc. What is the number of hours of daylight in the longest day of the year?

- The equation C = | 0.40 cos 1.20d0 and S= -0.40 sin1.20d0 are involved in the %3D %3D e study of damped oscillations. Determine the values. Ans C=0.66 and S = 0.41arrow_forwardSolve. Find the equation of a line normal to the curve of y-cos COS at x=1. 2 Select one: A. -3.3 x + 9y - 9 + /3 n = 0 B. -3,3 x + 3y + 3/3 - = 0 C. -6/3 x + 3y - Gu/3 - i = 0 D. 3 x + 3y - 3- 1= 0arrow_forwardThis problem is an example of critically damped harmonic motion. A hollow steel ball weighing 4 pounds is suspended from a spring. This stretches the spring feet. The ball is started in motion from the equilibrium position with a downward velocity of 5 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. Take as the gravitational acceleration 32 feet per second per second. (Note that the positive y direction is down in this problem.) y = learrow_forward
