Greetings Ma'am,
Ma'am I am a dropper and last year too maths bothered me a lot.
I had almost left maths a month back, somehow I got self realisation that though I am quite good in physics and chemistry but still maths do have an equal share in paper. I just opened your lecture and believe me, from now on i will atleast do a lecture of this series per day and will score at least 40 in maths
Bro 33:40 pe a=b jaise aaya subtract Karne pe to nahi aaya
ok but better to show solving step
2:54:12 you should slove this question by the process
Find a2-a1 and b1 b2 then determinate the value of a2-a1 ,b1 & b2 ..and when use determinate,use ---det[]=0
my test marks increased in mathematics after studying from you ma'am thank you so muchh

at 33:41 my ans is not coming mod a = mod b ??? i solved it twice it is coming 2a = b
on solving both equations, we will be getting |a|=|b|, and required angle as 60 degree.
stepwise solution is attached in pdf, kindly check.
Is it for jee 25 syllabus?
Can anyone please explain 1st question mein a aur b kaise equal aaye ?????
