Answer One Question from each unit

UNIT I

I. (a) Obtain a Fourier Series for f (x) = x sin x, 0 < x < 2p

(b) If f (x) = p x, 0 = x = 1

= p (2-x), 1 = x = 2, show that in the interval (0,2),

(OR)

(c) Obtain Fourier Series for the function f (x) given by ,

,

Hence deduce that

(d) Obtain a half range sine series for f (x) = x- x2 in (0,1).

UNIT II

II. (a) Find the Fourier Transform of f(x)= 1-x2, 1x1= 1

0, 1x1 > 1

Hence evaluate

(b) Express the function f (x) = 1, for 1x1 = 1

0, for 1x1 > 1, as a Fourier ritegral

Hence evaluate

(OR)

(c) Obtain the constant term and the coefficients of the first sine & cosine terms in Fourier Expansion of y as given in the following table

x: 0 1 2 3 4 5

y: 9 18 24 28 26 20

(d) Find the Fourier Cosine transform of f (x)= e-ax, (a>0)

UNIT III

III. (a) Find the first and second derivatives of f(x) at x = 1.5 of

x: 1.5 2.0 2.5 3.0 3.5 4.0

y: 3.375 7.000 13.625 24.000 38.875 59.000

(b) Find an approximate value of log e 5 by calculating to 4 decimal places, by Simpsons Rule dividing the range into 10 equal parts.

(OR)

(c) Using Range Kutta Method of 4th order compute y (2) and y (4) from , taking h = 0.1

(d) Apply Eulers method to solve y1 = x + y, y (0) = 0, choosing the step length h = 0.2 (carry out 6 steps)

UNIT IV

IV. (a) Find by Taylors series method, the value of y at x = 0.1 & x = 0.2 to five places of decimals from

(b) Find the value of y for x = 0.1, by picards method, given that

(OR)

(c) Solve the equation y11=x+y, with the boundary conditions y (0) = y (1) = 0.

(d) Determine the value of y at the pivotal points of the interval (0,1) of y satisfies the

boundary value problem

UNIT V

V. (a) Find K so that the following can serve as the probability density of a random variable

f(x) = 0, x = 0

(b) If the amount of cosmic radiation to which a person is exposed while flying by jet across the united states is a random variable having the normal distributions with Mean = 4.35 mrem and s = 0.59 mrem, find the probabilities that the amount of cosmic radiation to which a person will be exposed on such a flight is (i) between 4.00 & 5.00 mrem (ii) at least 5.50 mrem

(OR)

(c) If 20 % of the memory chips made in a certain plant are defective, what are the probabilities that in a lot of 100 randomly chosen for inspection

(i) at most 15 will be defective

(ii) Exactly 15 will be defective
