we have many short cuts in maths
like for sum of n terms
put n=1 or 2
similarly in binomiall u can put desired value of r and n
in trigonometry angles can b put as u want them
like in conditional specially
get all a b and c as 60 degree

some tips............
#Some questions may have cunningly designed elaborate answer choices just to
mislead you, like the following.
Qn. The number of tangents to the curve x2 + y2 = 25 through the point (2,3) is
(1) two, given by -12(x2+y2-25) = (2x + 3y ? 25)2
(2) only one, given by 2x + 3y = 25
(3) 0
(4) four
Ans. The given curve is a circle with origin as centre and radius 5. The given point
(2,3) is at a distance 223+ = 13 < 5, the radius, from the centre; hence the
point is inside the circle and therefore no tangent is possible.
Ans choice: (3)
.
#. Verification Technique
Qn. The system of equations???has the solution (x,y,z) =
(1) (2,3,0) (2) (1,2,-3) (3) (0,-1,4) (4) (2,4,1)
Ans. Real solving will be lengthy and not necessary. Verify which set of values satisfies the given equations.

distance b/w 2 parallel lines ax+by+c=0 and ax+by+d=0 is given by I d-c I / root(a2+b2) here d-c is in mod i.e. it is always positive cheers!!!! and best of luck brainbank.i wish you success!!!!!!  |
there are numerous options besides I.I.T

in the expansion of (x + y)12
to get the sum of all the coefficients of the terms, put x = y =1
so the answer is 212
