The Taylor series expansion for a^x is: a^x = sum n = 0 to infinity [(ln(a))^n]*x^n/n! Write a MATLAB program that determines a^x using the Taylor series expansion. The program asks the user to type a value for x. Use a loop for adding the terms of the Taylor series. If Cn is the nth term in the series, then the sum Sn of the n terms is Sn = S(n-1) + Cn. In each pass calculate the estimated error E given by E = abs((Sn-S(n-1))/(S(n-1))). Stop adding terms when E < .000001. The program displays the value of a^x. Use the program to calculate: (a) 2^(3.5) (b) 6.3^(1.7) Compare the values with those obtained by using a calculator.

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg. m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
