A ship is moving with an acceleration that is proportional to its velocity (dv/dt= kv) If its initial velocity is 8m/s and 10 seconds later is 7m/s find: i) value of k to 3 sig figs and give equation for the velocity of the ship. Thanks so much :)

Apply Simpsons Rule with five function values to find the volume of solid of revolution formed by rotating the curve y=sinx + cosx about the x-axis b/w x=0 and x=2pie Thanks heaps! :spin:

Hi I was just a bit confused and wanted some clarification - what is the limit as x approaches infinity of the function cos(x) and Why does 1-sin(x) have no limit as x approaches infinity? Thankyou so much for the help :)

Consider f(t)=t^6+t^5-t^4-5t^3-6t^2-6t-4. Given -1+i is a root of 'f' and that 'f' also has two real integer roots, factorise f into complex factors Thankyou heaps :D
