hey goiitians i have got a good idea over here

well iam planning to help all my friends with shortcut formulae in all subjects

u can lend a hand too

all u have to do is to post any shortcut formulae for any concept and specifying the subject u can brief about its applications.

u can rate the formulae u liked the most

get ready frenz lez start now

amarswamy

all viewers requested to pos a shortcut trick here
rates assured
u can rate me too if it was useful

actually i hav asked d same few days ago
but i was told tht thier r many threads on this particular question
so u can search shortcut or tricks.
and u knw chimanshu yaar usne to apne sare article shortcuts pe hi likhe he so u check thm.

par to bhi tere liye khas formulaes:
1)if we r asked to find foci of an ellipse
thn it is S=(+or- root of a^2 - b^2, o)

2)angle betn the tangents to the circle frm any point p(x,y)
angle =2 tan^-1 a/ square root of s1
where root of s1 is obtained by putting x,y in given eqn and a is d radius.

but actually mujhe lagta hai ki u should prefer books for shortcuts
like dinesh, vidyabharti and gayakwad (4 state board).
and remember maths 2 me shortcut se jyada practice important hai
so best of luck.
