Title: Working out questions in Methods
Post by: Domain on October 16, 2015, 08:59:00 pm

Okay so I have a question in regards to showing your working out in Methods. Since I do both Methods and Specialist subjects, some topics tie in within each other, especially intergration.
So my question is am I able to show specialist working out (using u substituion) in Methods examination questions or do I have to use the methods way of intergration? If you don't know what I'm talking about, look at the image below this post.
Thanks

Ah... I'm pretty sure the u substitution in this case is in the methods course. Although I don't what's so hard about going straight to the answer with this particular question - it's not that complicated :P

I think many methods teachers (at least mine) teach the 'anti chain rule', which is the equivalent of a short cut u substitution.

You can use any method of working out as you want :)

Wait, so as long as you get the correct answer and you show your thought processes as you did it, you get full marks?

Yeah and it's mathematically appropriate
So no trial and error
