APPLIED MATHEMATICS – II

Differential Equations:

1. Exact differential Equations and those which can be made exact by use of integrating factor. Integrating factor by inspection,

Linear equations & reducible to linear (Bernoulli equations), method of substitution to reduce the eqn. to one of the above forms.

2. Linear Diff. Eqn. of nth order with constant coefficients, complimentary function & particular integral when the function of the integral on the R.H.S. are exponential, Sin(ax + b), Cos(ax + b).Cauchys Linear equation( Homogenous eqn.). The Legendre Linear equation, Variation of parameters & method of undetermined coefficients.

3. Elementary application of above diff. Eqn. in solving engineering problems from Electrical Engg., Chemical Engg., Mechanical Engg., and Civil Engg.

Integral Calculus: Rectification of plane curves, Double and Triple integrals, Their geometrical interpretation & evaluation. Evaluation of double integrals by change of order and change to polar. Application of double and triple integrals to areas, volumes & mass.

Beta & Gamma Functions:

1. Beta & Gamma function & their properties, relation between Beta & Gamma functions.

2. Error Functions.
