thats cool, i just didn't want to make the problem ia hold lot harder, if it was cos2x then that would be insane

you used -k i used k which is right

thanyou very much but is this corect, or is it x = cost 2t - sin 2t

the simple harmonic one at some point we had to convert an equation with both sin and cos in it, in to just cos

the rate that somthings temp chages is proportional tp the out side temp there fore T = temp of iron t = time A = temp of freazer K, C are constants dT/dt = k( (T - A) by intergratioon we can work out T = A + Cekt at t = 0 T = 150 150 = -10 + C C = 160 T = -10 + 160ekt...

7 a i does any one have that question/ the answer any help would be grealty appreaciated

high 50's low 60's out of 84 i recon

A = pi I(pi/6 --> 0) cos22x dx = pi/2 I(pi/6 --> 0) (cos 4x + 1) dx = pi/2 [(sin 4x)/4 + x] (pi/6 --> 0) = pi/2 (root3 / 8 + pi/6) = pi root3 / 16 + pi2/12

i think we are unlikley to get a quesyion that is as ambigious as that and if we did both would be correct

Question 18 show that (x-1)(x-2) is a factor of p(x) = xn(2m - 1) + xm(1 - 2n) + (2n - 2m) where m and n are positive intergeres

somthing that is in the 4uint sylabus but can still technically be done by a 3uint student.

what do you meen new syllabus, it hasn't changed in like 18 years of somthing like that

i think i only used it for checking stuff like the cos 2pi/5 question

it would take me a long time but i think i would eventually if i had got to the stage of being married then i dont think so
