..which is why i used the word beneficial/favourable.. Advantage, beneficial/favourable..they all mean the same thing..don't they??:) -

U see if u had to produce large amounts of something...using Batch culture u would need larger vessels coz u harvest a batch at a time..whereas in continuous culture small vessels would suffice coz u know products can be removed as they are produced and reactants are kept adding continuously.. -

They are just examples u'll need to quote when explaining reflex actions.. So yeah remember the 5 sense organs and their receptors eye - rods and cones ears- Hair cells Nose - Olfactory cells Tongue- Taste buds Skin - Pacinian corpuscles for pressure and Meissner's corpuscles for touch.. -
Math 32....how was it? :/
(1/sin2x) = (1/cos x) + (cos x/sinx) (1/2sinxcosx) = (1/cos x) + (cos x/sinx) multiply each by cos x (1/2sinx)= 1 + (cos^2 x/sinx) Multiply each by sin x 1/2 = sin x + Cos^2 x write cos^2 x in terms of sin x 1/2 = sin x + (1-sin^2x) It comes down to Sin^2 X- sin x-1/2=0 2Sin^2 X- 2sin x-1=0 -
Math 32....how was it? :/
Yeah its pi ( y )^2 and to find the volume u integrate it! -
Math 32....how was it? :/
I did it (ln x)^2 and got the same answer as u did!! So may be it doesnt make such a big difference coz u have integrated in the same way..and Got the Right answer.. -
how was Maths pure 32?
I guess the Vector Question And the Argand one proving it to be pi/4 was hard.. Other than that the Paper was kinda Okay.. -
