i am facing problem solving tough questions in ellipse, parabola, circle, st lines etc

can u rcomend me some book or some method so that i can improve my math!

use tmh or akash material

Try Arihant publications book for coordinate geometry. they have loads of solved examples to start with. Also try sums from Ap board of intermediate level textbooks. They pretty much cover the entire syllabus. Also if you are stuck with any problem, post it in this space so that I could guide you further

Be thorough in formulas. Only then will you get new ideas, in analytical geometry.

Books=

1. R.D.Sharam

2. Arihant`of math............etc

Method:

ellispe>   b² = a²(1-e²)

Parabola>  Same method 

circle> no any hard method. you know that!

st.lines> no simple method. 

some important books for you: 

1. K.p.basu (for geometry made easy)
2. hall and knight 
3. 9higher alebra)
4. s.l.loni (for plane co-ordinates)
5. Dr. gorak parasad (for  co- ordinates geomerty)
