hey frnds plz tell me how to practice probability.....
its not too much sure in the exam if the answer is coorrect.......
and also its 10 marks weightage in exam.........
and wat do u except where the paper questions will be asked from???
will it be totally ncert based or from other book too like RD SHARMA ,malhotra etc?????
thanks..........

[kauser]

for probability practice all the text questions...first be thorough with the formulas adn the types of questions....I think text book is enough because the previous years questions dont show alot of variation
as for extra questions, I am doing previous years questions....for integration its a must.

Can anybody pls advice for relations and functions???are you guys going for some extra questions???
thanx

i think majority will be text like questions in the exam hoping so....

[sweet1]

first of all finish ncert text b'cos its the basic...
thn if u have enough time,thn opt 4 any additional books like R D SHARMA n others.....
u may also practice wid previous years questions, sample paper questions etc..
if ur basic is clear thn wats the prob....
never mind 4 the questions thn....
solving R D SHARMA doesnt mean the questions will be asked frm it, but its just 2 practice a variety of questions...
first complete ncert text's each n every question thn practice pre yrs queries....
b'cos i dnt think v have a lot of time....


n 4 rel n fun.. first practice out ncert book thn solve pre yrs ques......
most probably the questions will be frm proving part in the fun...
into fun, onto fun, combined funs etc.....
n dnt 4get 2 study basic topics......


neways. ALL THE BEST

hey frnds
solving graph questions i solve it by using graphical technique.......
should i use the same methond insolving question on functions Definite integrals increasing decreasing maxima minima or should i go through pure analytical method????
thanx

[kauser]

analytical becoz thats how its supposed to be done as the per the syllabus

[scorpionmanace]

ok frnd......

[sweet1]

choice is regarding wat u find the easier way 2 understand the concept or the topic.....
but the best way is do it analytical....
its the most preferd way

[scorpionmanace]

ok smriti.........
plz try solving this.......
integral [(1 - (x)^1/2)/ (1 + (x)^1/2]^1/2

[kauser]

make substitution as x^1/2 = cost

do all simplification........

before changing the integral back to dx..write for sint= (1-cos^2 t)^1/2 adn for sin2t= 2sintcost = 2cost(1-cos^2 t )^1/2

and change all cos^2t= x adn cost = x^1/2

you wont any problems...hopefully
