Mathematics: Post your doubts here!

[PhyZac]

PhyZac .. do u think M2 is easier or S1 ?

It depends on you actually.

I would greatly recommend S1,
It is easier for me than M2, as well as give you good knowledge for future!!

The hard topic shall be permutation and combination, what you need is little practice and then nothing is hard In Sha Allah.

PhyZac .. do u think M2 is easier or S1 ?

I'm personally going to take S1, as it has been said to be easier, and would be of great assistance in the field I'm aiming for (In Shaa Allah).. Medicine. As medicine in Uni includes a Bio-statistics course.

PhyZac ; for no. 4 (ii) , what value should I take as x1 ?

PhyZac .. do u think M2 is easier or S1 ?

and for me M2 is the best as i was never good at statistics

PhyZac ; for no. 4 (ii) , what value should I take as x1 ?

take something less than 90 degrees (1/2pi) because logically the angle looks smaller than 90 degrees i would say start with 1.5

I took pi, as x1.

Why, I dont know!

mechanics is always better than stats..stats EWWWWWWWWWWWWWW

Pls help me out for 2nd part of complex numbers question relating argument...

 

[Dudu]

Quick Question:
Is 2cos^2 x+2sin^2x=2?

 

[PhyZac]

Quick Question:
Is 2cos^2 x+2sin^2x=2?

Yes

2(cos^2 + sin^2)
2(1)
2

 

[Dudu]

Yes

2(cos^2 + sin^2)
2(1)
2

Cheers

i prefer the s1 and m1 combo even fot those who are poor at stats (like me ). it will help commerce and humanitarian science student as they will get a idea of mechanics and also do stats which is directly related. for science welll we have a full fledge course for stats in bachelers . for medical i gues stats might help and mechanical is purely physics

9ii put x=0 in eq of tangent and ssee if value of y coordinate is above 1.5 so nearer to B otherwise O

 

[Mayedah]

from solving first part you are able to get to sinx=0.5 . now if you compare both equations the only diff is n so we can say that
30/10=n hence n= 3 now for greatest solution find all solutions up to 3 x 360. then divide the highest with 3 you will get the answer

Thankyouu soo much i got it now

Please help me with question 2, I don't know what to do.
Thanks

sin 3x + 2cos 3x = 0

divid the equation by cos x and u will get tan 3x +2 = 0
tan 3x = -2
3x = -64.3 and 116.5
x= 158.9 and 38.9 but i have no idea how the mark scheme got 98.9 as one of x values sorry :/

can anybody please explain how you put work done, work done against resistance, PE gain/loss, KE gain/loss in an equation? im lost (( thank you!!
