@Brooklyn Maine pehle assume kiya ek jane ne 5 sahi kiye.. usse distinct nahi aaya kisi bhi case me
then maine assume kiya ki ek jane se saare galat kiye hai.. and 0,1,2,3,4 are the distinct correct answers.. usse Dorris aaya .. Par saala bahut time laga ! :banghead:

Bahut random hai ! uff..

Trignometric formulae :-

1) sin (-x) = - sinx

2) Cos (-x) = cos x

3) Sin (x+y) = Sin x cos y + Cos x sin y

4) Sin (x-y) = Sin x cos y - cos x sin y

5) Cos (x+y) = Cos x cos y - Sinx siny

6) Cos (x-y) = Cos x Cos y + Sin x Sin y

7) tan (x+y) = (tan x + tan y)/ (1- tan x tan y )

8) tan (x-y) = (tan x - tan y)/ (1+tan x tan y)

9) cot (x+y) = (cot x cot y - 1)/(cot x + cot y)

10) cot (x-y) = (cot x cot y + 1)/(cot y - cot x)

11) sin 2x = 2 sinx cosx = 2 tan x / (1+tan^2 x)

12) Cos 2x = cos^2x - sin^2x = 2 cos^2x - 1 = 1 - 2sin^2x =(1-tan^2 x)/(1+tan^2 x)

13) tan 2x = 2 tan x/ (1-tan^2 x)

14) Sin x + sin y = 2 sin (x+y/2) cos (x-y/2)

15) Sin x - sin y = 2 cos (x+y/2) sin (x-y/2)

16) Cos x + cos y = 2 cos (x+y/2) cos (x-y/2)

17) cos x - cos y = -2 sin (x+y/2) sin (x-y/2)

18) 2 cos x cos y = cos (x+y) + cos (x-y)

19) - 2 sinx siny = cos (x+y) - Cos (x-y)

20) 2 sin x cos y = sin (x+y) + sin (x-y)

21) 2 cos x sin y = sin (x+y) - sin (x-y)

maine bhi yahi kiya..ek case me betty k zyada aaye..doosre cases solve karne ka mann nai kiya to betty likh diya :splat:

@nits2811 try this.... calculation base..

look at smaller example if it was 2

it would ring tiwce n there wuill be gap b/w 2 rings = 1

so

7 bell will have 6 interval
thus 6t= 7
so we have to find 9t 😃 use unitray
