REVISING MATHEMATICS-LAST MINUTE PREPERATION-(II PUC)

THIS ARTICLE IS FOR THE STUDENTS WHO ARE IN LAST MINUTE PREPARATION.

It is very difficult to mention important questions  in mathematics. Because the direct questions what everybody list as important questions   in other subjects will not  appear in  mathematics.

But patron of the questions will be same as in previous year question papers.  practicing  problems of  previous year questions  is enough to prepare for Mathematics.

If u are selecting, complete the following areas:

ALGEBRA

Matrices and determinants:

a)Solving the simultaneous equation by cramer’s rule and matrix method

b)Statement of cayley Hamilton theorem and finding inverse of matrix and verifying cayley Hamilton theorem

Vectors

a)Application of vectors like: proving sine rule, projection rule, cosine rule, compound angle formulae, angle in a semicircle is right angle by vector method

b)Problems on scalar triple product and vector triple product.(standard problems)

c)Find the projection of one vector to another vector , find the sine or cosine of angle between the vectors, unit vector in the direction of vector,

Groups

a)Proving a particular set forms an abelian group like Show that a*b=a+b-ab forms an abelian group, Show that G={5^n, (integral multiples of 5) } forms an abelian group etc  refer topic wise questions in mathematics in this website.

Elements of Number theory :

a)Finding GCD of two numbers and representing them as a linear combination of x and y and showing x and y is not unique

b)Find the number and sum of divisors

c)Finding the last digit or unit digit, solving linear congruence.

TRIGONOMETRY

INVERSE TRIGONOMETRIC FUNCTIONS:

a)problems on use of formula tan^-1 x + tan^1 y= tan^1(x+y/1-xy)  etc

b)problems on this,  see topic wise questions in this website.

CIRCLES

b)problems on finding centre , focus, directrix and ends of Latus rectum of parabola , ellipse and Hyperbola,

c)Definition of rectangular hyperbola, director circle, auxilary circle and its equations

DIFFERENTIATION:

a)problems on differentiation from first principles: no need to solve differentiation of inverse trigonometric function by first principles and some problems like  root sinx, sinrootx etc.

b)problem on successive differentiation, logarithmic differentiation , parametric differentiation

implicit differentiation (refer topic wise questions- it contains limited number of questions).

APPLICATION OF DERIVATIVES

a)Problems on Derivative as a rate measure, problems on finding maxima and minima involving 2 dimensions figure only( Don’t go for problems on finding maxima and minima involving figures like , sphere, cylinder, etc)

b)Angle of intersection between two curves: like: If ax^2+by^2=1 and Ax^2+By^2=1 cut each other orthogonally , show that 1/a-1/b=1/A-1/B

INDEFINITE INTEGRAL:

a)problems on forms of integral, all types

DEFINITE INTEGRAL

Proving  some properties of definite integral, and problems using definite integral.

AREA UNDER A CURVE

See topic wise questions in this website.

DIFFERENTIAL EQUATION

a)Finding order and degree of Differential equation.

b)Solving Differential equations by variable separable method (see topic wise questions)

At last:

And so on……………………………………………………………………..

Count the marks  you will get more than 35 marks

So it is easy to prepare for mathematics examination .

Excuse for spelling and grammatical mistakes

so

BEST OF LUCK .
