URgent hhelp!! is Casio FX-350ES Plus aloud for AS math. exams?
If it gives answer in numerical form(not symbolic) then it is allowed. -
Mathematics: Post your doubts here!
hypotenuse AC is itself 16. cos(pi/6)=BC/AC which gives BC = 8*3^(1/2). sin(pi/6)=AB/AC which gives AB=8. The perimeter is (8+16+8*3^(1/2)) which is what the question requires us to show. Angle B is 90 degree because AC is the diameter and B is on the circumcircle. :) (I could give a... -

ABC is a right angled triangle. Angle subtended by diameter is always 90 degree. So angle ABC is 90. angle c will be half of (pi/3) that is (pi/6). so you just use sin and cos with the hypotenuse AC equal to 16. So no need to use cosine rule and stuff. It is just o level maths knowledge. -

in trigonometric equations, you should always use the range of sin, cos, and tan. in this one, f(x)=3-4cos^2(x) , you know that -1=<cos<=1. So 0=<cos^2<=1 as -1 becomes 1. Since we have negative 4cos^2, we reverse the signs and multiply by 4 to get 0=>-4cos^2>=(-4). Then simply add 3 to the... -

ii) First you have to realise that boxes do not have to slide. We know the mass of A which is 200 kg and can calculate the vertical contact force which is equal to weight i.e 2000 N. Multiply the C. of friction i.e 2000*0.2 to get 400 N. It means that this is maximum force which the box B... -

First you have to find the displacement of P which is equal to that of Q as is given. Integrating (3t-0.3t^2) with limits 10 and 0 gives you the displacement. Then simply assume greatest speed to be v and find area under graph given i.e 0.5 *v*10 and equate it with the displacement found. I... -

taking derivative: 3x^2 + 3(y^2)y'=3y + 3xy' (1) (cut the 3s out) >> x^2-y = (x-y^2)y' >> if y'=0 then x^2=y using the original equation: x^3 + x^6=3x^3 >> x=2^(1/3) and y=2^(2/3) taking derivative again of (1): 2x + 2y(y')^2 + (y^2)y'' = y' + y' + xy'' >> since y'=0 , 2x + (y^2)y''= xy'' >>y''... -

take 2^2 common and apply the sum of squares method. :) -

Well this part follows the previous part of sketching the graph. Also it is an easier method. -
Mathematics: Post your doubts here!
(Cosx-1)^2 = (1-cosx)^2 because minus sign taken common becomes plus due to the square. -

It is 90 degree. You can draw a graph and look at the value for which the function is one to one. Use tan=sin/cos first and then open the square. The combine the fraction and use sin^2=1-cos^2. Use the difference of squares identity and cut the '1-cosx' from the numerator and denominator. And... -
AS Maths
I am giving as maths this session. It is quite good enough for an 'a' grade in As level but you can't say anything about A2. A lot depends on the other three papers especially P-3 which is more difficult than P-1 You should look at the past GTs. But anyways you should aim higher and not just get... -

how to solve these similar triangle questions
simply draw good diagrams and apply properties of parallel lines, similar and congruent triangles properties. Use SAS property in first one, corresponding equal angles by parallel lines in the second question, ASA property in the third on and again SAS property in fourth one and simple... -
Career
In pakistan, computer and electronic( telecom) engineering can be done only in engineering because chemistry is a requirement for other eng fields. However, you have so many other opps like ca, acca, econ, bba and mba, b.com m.com, bs in maths, physics etc. It depends on your aptitude and liking...- shezi1995

Accelerated Maths! Plz Help
If you have a teacher who will teach you the whole syllabus then why not? M1 is all physics as level but more mathematical and will be easy if you study physics. I can't say about P3 with surety but if you work hard then why not try it? You can always have a retake in your A2 year( assuming that...
