Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Oh no not again.
This I got I think
I meant to ping the math guys.
(eĀ²+e)/138
*128
Man, how do we even begin this?
Get dy/dx as an independent term.
Multiply throughout by -siny
Take cosy = z
First order linear in x and z
Oh.
I see.
Ye, it hurts on the inside once you know
Lmao, I'm cooked this time š„²
Considering I didn't get the NLM and work question.....
Can't even fathom to imagine what they'll do next year...
You remember that question about the ellipse and distance between foci?
That was amazing
The one today?
So simple.
Ye
Yeah. A bit lengthy tho.
The circle and ellipse one I reckon.
No, it was amazingly simple
Foci are dimetric end points, so angle at P is 90Ā° right?
Yep, I got the concept that the diameter subtends right angle and stuff
So product of lengths, sum of lengths is given.
But calculating L.R. and shi was calculative
12,5 are PF1, PF2
I got it tho somehow, yeah...
Then it's a right triangle
Pythagorean triplet
LR??
Oh I was confusing it with some other one sorry.
There was a fun GCD question which i assume you did
I got that wrong
In last minute hurry
I was panicking so much by that time I began manually counting them and then proceeded to leave it unattempted.
Lucky
Feels mildly frustating now that I think about it tho...
Yeah, I made a silly a** mistake
But still I presume you had to do case-working?
Combi works no?
gcd must be 1, so summation of phi(n), n=1 through 16 I thought.
GCD must be 6?
Yep, consider numbers to be 6k, 6m; k and m belong to 2 to 16.
i didn't expect lance out of all people to post a math doubt with the caption "no clue, just depression"
And they must be coprime
Man, I suffered 7 lifetimes worth of brainfarts today in mains lmao.
im terrified of this š
i suffer an absurd amount of brainfarts in mocks let alone the actual exam
When you're so cooked you begin laughing
friendship ended with mains š£ļø š„š„
Yeah, but if you take numbers to be 6k and 6m, k and m must be co-prime tho no?
So, it was basically summation of phi(n), n=2 through 16, which was very painful to calculate as far as I remember.
Yeah my bad, not phi(n) but number of co-prime thingies from 2 to 16.
Yeah sorry, I was underground
