that's pretty cool 😎 Alka ma'am, but how is that even true that's what bothers me now 😊 anyway I am gonna use the modified one that I had thought but you approved. Thank you so much, Alka ma'am.

vijay , please dont follow blindly. this formula is wrong . and calculation is also wrong . there is no formula like this in any book . please google and find by yourself. if i am wrong then please correct me.

how can u say that it is wrong....prove it

see also

it is photo ...which is take from a book ....see

this thing everybody know. it is for ratio test not for rabbe test.

plz give me valid reason why we can not apply that formula

i can prove that modified formula.......can you prove your sentence

it is not about proving or disproving. my concern is this only i didnot see this formula in any standard book which u have written . nobody wrote this formula and if student ask us something then it is our duty to verify atleast twice if we r writting something from our side.

dont do hurry to get points . bcoz students will take it as short trick whatever we write here. and if they get some wrong answer in exam then after no body can change that answer.

so if you write something which is not mentioned in any book .be precise and try to avoid these things. whatever we write do not neccessary it will always be right.

my aim is also to teach students correctly . In books alwys standard formulas or results are wrriten ...but they do not mentioned their modified form

not even raabe test ...all test can do in this form ....if this possible then discuss with any professor
