e have solved differential equations using the method of undetermined coefficients (Chapter 7) and Laplace transforms (Chapter 8). We can use Fourier series to find e particular solution of an arbitrary order differential equation - as long as the driving function is periodic and can be represented by a Fourier series. the problem description and answers, all numerical angles(phases) should be given in radian angles (not degrees). iven the differential equation y" +18y' +82y = 9cos(2t +1.5708) +5cos(4t-1.0472). a. Write the fundamental frequency that you will use for this system. Wo= help (numbers) b. Write the transfer function for this system as a function of n. (See page 530 of the text.) H(n) = help (formulas)

Question 10 What function is the general solution of the differential equation y" - 4y + 4y = 0 ? O y = e²z (Acos(2x) + B sin(2x)) Oy= Ae2+ Be² Oy=(Ax+B)e² Oy= A cos(2x) + B sin(2x)

Discret maths, please type the final answer clearly thanks
