But calculating g.p took a lot of time! How did you do it? I found it difficult, because we had two unknown variables.

But calculating R was long, wasn't it?

not at all

 

[Ram97]

But calculating R was long, wasn't it?

Umm.... Yeah
What was stationary value of u?

 

[Kruthi]

Umm.... Yeah
What was stationary value of u?

I don't remember!! Sorry!-_-

 

[Komail Sabba']

Umm.... Yeah
What was stationary value of u?

i don't remember, but i think 6

 

[Kruthi]

i don't remember, but i think 6

I think so

 

[Komail Sabba']

anyone attempted q6i? i got h=120m .. but i'm not sure

 

[DeadlYxDemon]

anyone attempted q6i? i got h=120m .. but i'm not sure

I got the same ans... since they said highest point or something so had to substitute pi

 

[Ram97]

I got -18 for stationary value of u

 

[Komail Sabba']

I got -18 for stationary value of u

if you can remember the values, i can send you my working in the inbox

 

[Zash Riyash]

Anyway... The exam is over, we can't do anything about it, can we? So let's forget about it, and focus better in the upcoming exams!

I don't remember!! Sorry!-_-

I can't believe this Kruthika! You couldn't get that one?

were you able to show that the triangle OAC is isosceles? 9iii

 

[Ram97]

were you able to show that the triangle OAC is isosceles? 9iii

Yup and do send me the workings

 

[DeadlYxDemon]

What u guys did was " -8/3 - (-8)
What I did was -8/3 - 8)

 

[Ram97]

And I guess your friend did 8/3-(-8)

 

[asadalam]

were you able to show that the triangle OAC is isosceles? 9iii

yup as |OA| = |OC| 2 sides equal so isoceles as magnitude was square root of 36 i.e 6

 

[Kruthi]

yup as |OA| = |OC| 2 sides equal so isoceles as magnitude was square root of 36 i.e 6

High five!

 

[DeadlYxDemon]

And I guess your friend did 8/3-(-8)

He did "-8/3 - ( - 8 ) & thus he got 16/3 pi

 

[asadalam]

What were the values of c? i got something like 2.5 and -3.5 or smthing
And what was theta in that tan theta wala q?I got 80.5 and 135.And that angle in vectors was it 31.8?

 

[DeadlYxDemon]

yup as |OA| = |OC| 2 sides equal so isoceles as magnitude was square root of 36 i.e 6

I lost a mark here. ..

 

[asadalam]

Were you guys able to prove that trig identity?I got it at the last min ^^
