Do not go where the path may lead. Go instead where there is no path and leave a trail.

I do apologise, I have made a mistake in the calculation, the correct solution should read 273 / 348 * 60 = 36.9 minutes (3.S.F.)

Perfect, except that it should be -110 instead of -100 :D

By the way Adi would you be kind enough to go through the forumla sheet on differentiation and integration that I have posted on the first page of this thread ? Thanks :D

I did, i cudnt find any errors. however the product rule and quotient rule, this is easire to remember

dy/dx (uv) = v(du) + u(dv)

dy/dx(u/v) = (vdu - udv)v^2

P - locate it roughly from the origin , using 280 and -40. like roughly 280 units to the right, and 40 down(-)

Q - again, from the origin , 50 to the right and -70 downwards, however this time u gotta make a parallel line to that one joining the OP ...this is to complete the triangle...

its actually from P, but just FYI, how it comes dere, it shud be taken from O, but to complete the vector triangle , a parallel line is taken from P.
