i got 95...shoulda got abit better tho i thought i nailed it

oh by the way that is wat i wrote and got 2 marks, the catholic answers said: x= cos2t-Sin2t x= sqroot2 (1/sqroot2 cos2t - 1/sqroot2 sin2t) = sqroot2 (cos pi/4*cos2t - sin pi/4*sin2t) =srroot2 cos(2t+pi/4)

Sorry it is cos2t-sin2t

Answer?

Thats question 6 a: "a partivle is performing SHM about a fixed point O on a straight line. At time t seconds it has displacement x metres from O gien by x= cos2x-sin2t i) Express x in the form Rcos(2t+@) for som R>0 and 0<@<pi/2 ii) find the amplitude and period iii) determine whether the...

q7ai is the easy part...do u mean 7b?

Yes, the projectile one?

if its rotated about the x axis doesnt it mean the integration is y^2 dx?? i always thought that was the case??

Guys, lincoln wont be specified again...i wouldnt bother learning him if i were u Otherwise, i agree that atwood and cicero would be the worst- atwood isnt even a proper speech lol And just basically know the techniques used in each one- if u forget the quotes for the specified speech, just...

Yes, u write in first person although sometimes you can get full marks writing in third ie 'one's understanding of transformations is broadened...' Last years question was VERY similar to the one u wrote, have u seen some of the standards answers? Basically you can say that transformations has...
