Also explain some questions regarding different centres of triangle..
In Q. 56 Paper-1.acc 2 me using the prop. that angle in a semicircle is 90, the 3 vertices should lie on a semicircle as angle is 90 and one vertex lies on the circle…

Bhaiya,
In the mock test 2 question 43 of paper 2 which you discussed in our last class actually g(x) has [x-f(1)][x-f(2)][x-f(3)] in denominator, so when you replace f(2) in g(x), g(x) is not defined
and also f(2)-f(3) is negative so overall g[f(2)] becomes positive.That’s why most probably in the solution it is given positive.
Bhaiya plz discuss this question again as we cannot put x=f(1) or f(2) or f(3).
yes bhaiya if u can tell some ideas how to approach questions related to orthocentre,incentre,circumcentre…..

bhaiya stop taking classes
i took 5 of them and i lost all my comfidence
r u mad dont listenn to him
bhaiya they are really helpful
l
I understand your point but there are students who wants to understand the questions that are being asked in Advanced Mock test. So I would suggest that you should not attend these classes if you are loosing your confidence.

find the coefficient of x^3 in the expression !
what can be the shortest way??
i am getting -49/8 as my ans but very long method!
yes bhaiya please tell how to go for this ques??
SOLVE:

a unit vector at t=2 on the curve:-
x=t^2 +2 y=4t-5 z=2t^2 – 6t
please discuss this ques and please tell if we partial diff. x and y and z then do we get vector in the plane of tangent to the curve???
