Syllabus doubt

Spheres isn’t given in Advanced syllabus but given in Arihant. So it is in syllabus or not? Neither taught to us but i searched internet and found that it is taught in many coachings. I am genuinely confused. Haven’t studied it till now.

Its taught to us in coaching , its like circles only but with 1 extra vector.
It only has radius , plane as tangent and some small concepts.

It’s a topic given in Session-4 of 3D-Geometry in Amit Agarwal

I connected the formulas with 2D. It was a small topic.

Thanks guys. I studied basic of it and won’t focus any more on that.

Vector-3D is important though, right? 3-4 questions every year. 7 in 2013.

Vector is imp , i was talking of 3-D


See for yourself , 3D has 0% for 2018,2019 and 3% in 2017
And 5% in 2016 so its weightage is probably decreasing each year.

Bro?? @LaveshGupta

Bansal subjective exercise.

Can you send me photos of it please?? I need some material to solve for Vector and 3D…

Why photo when you have pdf? Bansal is proper closed so I dont mind circulating pdfs. There’s a rank booster at last for extra tough questions.
