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 thank you so much :) Another question to clarify: so why does the limit as x-> infinity of x+cosx = infinity? Sorry Im finding all this a bit confusing :)

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

find the y value of the point whose value is 7 if the point lies on the curve y=f(x) defined by f'(x) = f(x) Thanks :)

How do i find the domain and range of ln(x^2-5)?????

Show that Re(1-z/1+z) = 0 for any complex z with |z|=1 Thanks heaps for the help! :rolleyes2:

???? Thanks in advance! :)

If I swap a course, am I still able to choose what tuts I can go to or is it automatically chosen for me?

I mean I accidently pressed enrol into a course instead of remove, is there anyway I can get it dropped or something?

Thanks heap! The answer they had was so weird! The way you guys did it was way easier! :D

When the polynomial P(x) is divided by (x^2-1) the remainder is 3x-1. What is the remainder when P(x) is divided by (x-1)
