P1 Math doubts only!

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?

For C I got (9,7) and vector angle was 31.8 and theta one I screwed up

 

[DeadlYxDemon]

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

Nope!

For C I got (9,7) and vector angle was 31.8 and theta one I screwed up

That c is right but the other c in which there were multiple possible values

Nope!

Want me to tell you

i got the angles of tan as 71.3 and 63.4

and the vectors angle, same.

i dont remember the values of c, but similar

Want me to tell you

(9,7)YES

I don't know about the other c perhaps I skipped it
yeahh inbox me..
Thw Q was sin + cos -1 / sin + cos +1 ... not sure

Some of my friends got tan same,must mean i got them wrong :/

 

[DeadlYxDemon]

Tan/6 = tan (1/6) ???

 

[asadalam]

(9,7)YES

We had to replace sin with tan cos

tancos + cos/tancos-cos

cos(tan-1)/cos(tan+1)
cancel cos on both ends and we get tan +1 tan -1

What's your next exam guys?

 

[asadalam]

What's your next exam guys?

Economics on 13 and Physics on 14

 

[Komail Sabba']

What's your next exam guys?

paper 5 bio

 

[Kruthi]

What's your next exam guys?

Physics!

 

[DeadlYxDemon]

Mechanics is still left...

 

[Komail Sabba']

Mechanics is still left...

Mechanics is waaaaaaaaaaaay easier!

 

[Zash Riyash]

Oh, I'm doing physics next and I'm doing stats instead of mechanics.

 

[Kruthi]

Mechanics is waaaaaaaaaaaay easier!

Mechanics is all the vectors and stuff, right?

 

[Komail Sabba']

Oh, I'm doing physics next and I'm doing stats instead of mechanics.

i do both

 

[Kruthi]

Oh, I'm doing physics next and I'm doing stats instead of mechanics.

So am I, and I'm going to beat you in Statistics!

 

[Kruthi]

i do both

You mean you're giving statistics as well?
