Right way to rotate

[@jeesimplified-subject]

Do you like the new format 😅

[@maruthy1234]

Great 😂

[@akaalkiratsingh]

Format is great but try to improve the camera angle

[@siddharth4733]

I think this ques is present in cengage coordinate geometry

[@jeesimplified]

don’t worry, you ear phone is working just fine 😂

Maruti forest society me rehte ho kya?

[@ShashankChoudhary-vl8kb]

But if you remember that rotation matrix this becomes more easy nd fast!!

[@saifimam7009]

lets say the angle (b+2,a) made with x-axis is theta . so Tan(theta)=a/(b+2)
now , adding pi/4 in theta as rotation in anticlokwise will increase the angle with x-axis by pi/4.
we know the new coordinates are (-1/√2 , 7/√2) .
Tan(theta+pi/4)=(7/√2)/(-1/√2)=-7
=> Tan(theta) + 1/1-Tan(theta)= -7
by solving we get ,Tan(theta)=4/3
a=4 , b=1. so 2a-b=7

Rotation sunte hi physics walo ko rolling without slipping dimag mein aata hai, hamein complex numbers :)
Loved the bloopers 😂 keep working hard fam 💪

[@Aayan_200]

We can assume x= rcos theta and y=r sin theta
Then tan theta= y/x
Again tan (π/4+ theta) can be found
And distances can be compared
It shud be (a+b+2)/√2, (a-b-2)/√2

Hii bhaiii

Rotn matrix watching from hell🤔....

[@annanay007]

Solution?

💀damn , I missed!

Par mujhe to sab sunai de raha

[@vishwassharma3312]

Aap Agra m khaa se ho?

[@shikhasharma9526]

Same approach is used in vector too

[@BhanuPrakash-il4yp]

my head rotated 360 when i heard your voice only on the left side of my ear in headphones

[@jeesimplified-subject]

😂

[@doge_the_cat]

Yes lmao very easy i dont think anybody does the whole long method

[@sanjaykumarsingh129]

i did in same way

[@dineshrajgujjula4268]

bamboozled

[@BhanuPrakash-il4yp]

me who did it in less than 10 secs

[@TobiZet_9]

Are Einstein baba ap?😮

[@BhanuPrakash-il4yp]

@@TobiZet_9 bhai idk why but when i saw the question the first thing that came in my mind is parametric forms of transformed points 🤣🤣🤣
