and just to add to jesshika's explanation of plasmolysis, in plant cells the cell wall pulls away from the rigid cell wall and hence the cell shrivels....PS: once again shrivelling is bad terminology to describe plant cell plasmolysis
Attention: Mill has pointed out that i made an error in my solution...
After working out tan^-1(a/4b)+tan^-1(4b/a) to be pi/2 i forgot to substitue it back into cis[tan^-1(a/4b)+tan^-1(4b/a)]. So :
4/3xcis[tan^-1(a/4b)+tan^-1(4b/a)]
=4/3xcis[pi/2]
=4/3x[cos(pi/2)+isin(pi/2)]
=(4/3)i
Actually i do use microsoft equation found in your word processor (Microsoft Word)
Click on the Insert button then click on object..a list of all programs that allow you to insert objects would come up..search for microsoft equation then away you go...:)
Another program is MathType
Well it really depends on your HSC chem marks...if you scored between 75-100 in chem then COLA recommends that you do Higehr chem...
Another advantage is that since higehr chem is a relatively harder subject than fundamentals then you would be scaled up much better...e.g. a credit would move...
I don't know if this is relevant here but i've heard that the only classical language to be used in everyday life is Classical Arabic in the Middle East where it is used in writing letters, news, all printed material even ads..
Now that's quite interesting.
