Anyone got any predictions for what theorem is coming up for HL? My teacher has a feeling it will be Pythagoras theorem because it hasn't come up on the JC since the syllabus changed and it came up on our mock, opinions?
Pythagoras' Theorem (Theorem 14) is most likely to come up. However I would learn the circle theorem (Theorem 19) as it has came up frequently in the past few years.
Also, remember that Theorem 14 is proved by making 2 right-angled triangles with the main one, by using trigonometric ratios for each smaller triangle is to the main one, and by finally adding these two ratios together.
@SryanBruen actually, proving Pythagoras' Theorem has never came up in the New Project Maths papers, so I wouldn't be so certain. And it's hardly given in the log tables (nor is any other formal proof, for that matter) - otherwise everyone would just copy it straight out of them.
Ec2406 I have seen the log tables and it is in it. I don't mean it as a proof, I mean it as a separate thing in a question like Trigonometry where you have to find a missing side before finding the sin, cos or tan.
