Hi raj

thanks for asking your query ,no rd sharma is not enough for the preparation of jee mains therefore you should follow other books available online by indian writers ,for jee mains you should also finish your rd sharma each and every sums .

best of luck

Hello aspirant.

By converting D operator, the equation will be

(D^2+1)y=cosx-sinx

The complementary equation:

D^2+1=0

D=+j,-j

y(cf)=Aexp(jx)+Bexp(-jx)

y(cf)=Csin(x+a),c and a are constant

y(pI)=1/(D^2+1)*(cosx-sinx)

y(pI)=x*1/2D*(cosx-sinx)

y(pI)=x/2*integration(cosx-sinx)dx

y(pI)=x(sinx+cosx)/2

Complete solution:

y=y(cf)+y(PI)

y=Csin(x+a)+x(sinx+cosx)/2

Hope this will help you.

Hello P himabindu.

Your question is a little incomplete actually you have not mentioned your course.

But still if you are a non medical student then you have to study mathematics for at least 2 semesters and sometimes 3 semesters also. Syllabus is almost same but some colleges complete it

Hi, Alan,

To become an electrical / electronics engineer your physics & maths part should be strong & chemistry only you have to read in the first year only. In second year onwards there will be no subject of chemistry. So you must know only the basics of chemistry. But

Dear Student,

You can refer below recommended books for your preparation: 

1. Calculus - Thomas Finney
2. Real Analysis - Bartle and Sherbet
3. Linear Algebra - Serge Lang
4. Probability - Sheldon Ross

Good Luck!!

Hi,

Since you have not mentioned whether you want to find the aggregate of class 10 or 12, generally you have to calculate the highest marks obtained in the marksheet in 5 subjects orderwise regardless of what subject it is in class 10 while top 4 in case of class

• Graduation (B.Sc. (Bachelor of Science)/ B.Tech. (Bachelor of Technology)/ B. E. (Bachelor of Engineering), with Mathematics as one of the main subjects, completed from a recognized
