Tut4.pdfTut4.pdfHi i have spent a huge amount of time at these maths in the attached file, i was wondering if someone could help me out with mostly 3 but also 2 . Cheers

For q2 i get as far as:

S=L=integral of 0 to t , sqrt((12/t^2 + (sint)^2+(cost+tcost-sint)^2 but dont know where to go from here

For q3: i get T(t) but it is seriously complicated so when i go get T'(t) it gets even worse differentiation and it looks horribly wrong

Anyhelp in the right direction is greatly appreciated,

Regards,

Conor
