Semester End Examination


Unit I: 

Fundamentals: Mathematical functions, odd and even functions, Trigonometric functions, polynomial expressions, logarithmic functions, exponential functions, constants and variables, standard forms of straight lines and parabolic equations with graphs.

Unit II: 
Differential Calculus

Differentiation of simple functions like xn, ex, log x, higher order derivatives, partial differentiation of first and second order, total differentiation. Maxima and minima of one variable function.

Unit III: 
Integral Calculus

Indefinite integrals, integration of standard function, methods of integration: integration by substitution, integration by parts, integration by means of a partial fraction, definite integrals and their properties.

Unit IV: 
Numerical Calculus

Roots of quadratic equations analytically and iteratively (e.g. pH of a weak acid). Numerical methods of finding roots (Newton-Raphson, binary –bisection, e.g. pH of a weak acid not ignoring the ionization of water, volume of a van der Waals gas, equilibrium constant expressions), numerical integration (Trapezoidal and Simpson’s rule, e.g. entropy/enthalpy change from heat capacity data).

Unit V: 
Mathematical Series and Statistics

Power series, Maclaurin, Taylor series, basic concepts of probability distributions (gas kinetic theory) and mean values; Binomial (gas kinetic theory).

Note: Calculations involving use of calculator is to be avoided.
