Title: Are you allowed to use specialist techniques in Methods
Post by: JackSonSmith on April 05, 2015, 07:09:33 pm
I was told by a methods teacher that when investigating points of inflexion in methods, we will not receive marks if we find the second derivative and use it to determine the nature of points of inflexion.

If that's what your teacher says, you listen. Never go against your teacher when it comes to SACs.

For the exam, however, you are allowed to do anything that is mathematically correct. HAVING SAID THAT, you should always try to use methods techniques on your methods exam.

Going against what your teacher says is a recipe for disaster.

Don't SACs have to abide by VCAA guidelines though?

Given that your teacher is marking your SAC...I'd say it's a gamble to go with VCAA guidelines against your teacher's instructions.

But when push comes to shove, VCAA's opinion would trump anyone else's. Couldn't you theoretically appeal to them and get your marks back?

But yeah, I guess it's a lot easier if you just go along with what they say lol. Just use a gradient table to verify the nature of stationary points.

Then, your teacher forever thinks of you as the kid who told them off to VCAA. :P I've had a friend who did this, and it did not go well.

If you have worked part time at Macca's before, just think of your teacher as a customer. Whatever he/she says, goes.
If your teacher  wants you to use methods techniques for a methods test, then you better damn well give him/her fresh chips.
