geomtery in hsc? (1 Viewer)

do u see circle geometry and geometry in yr 12/?? or is it in the HSC.. ?? does it get any harder than the year 11 stuff.. this does not include furthur trig - t formula, compound angles etc...

Yes, unfortunately. A trial paper I did a couple of days ago had a pretty long circle geometry question.

However, the t-formula had never been seen again after learning it in year 10.

Build up a solid maths foundation in year 11. Do your exercises and remember the formulae - you'll need most, if not all of it next year.

u learnt t formula in yr 10??? we never learnt it.. but foruntately i did it in tutor..~! lol...
its not very hard.. just substitutions to cos, tan, sin as i remember

If you do extension 2 you'll face circle geometry questions that will make what you're doing at the moment look like times tables.

dreamish~~ can u also show me that geometry question i would like to see how the geometry is in the hsc thanks

LOL omg, I got the t-formula mixed up with something else which also used "t". You mean t-formula in trig, yeah? Well that you DO need.

The question from the past paper was (now that I look at it, I wasn't long as it was just one question, lol.)

The points A, E and C are co-linear. Prove that ABCD is a cyclic quadrilateral. (See graph)

lol i cant wait to learn integration at school, already learning at tutor quite easy, confusing at first until the teacher told me that it was the reverse on differentiation.. differentiation was all good 100% in topic test aiming for 100% in integration locus was a bad topic lol.. interpreting those geometry and locus questions are hard lol im not that much of a visual person lol

is that all the clues they gave you? is AB and CB the tangents??

Yep, that's it. AB and CB are tangents, but they are tangents of different circles. Tangents from the same circle that meet at X are equal, but this rule doesn't apply when it comes to two circles.

shouldnt they tell you that they are tangents??.. i could see that they were but.. they should of said it thought right?

what past paper is this from dreamerish~??

what past paper is this from dreamerish~??

Well, they don't have to. You can see that they are tangents because they touch the circles without intersecting. I'll give you a hint. Focus on what information they did give you - A, E and C are co-linear. That makes ACD a triangle. Work from there. Also, remember the rule of cyclic quadrilaterals?

This was from my school, last year. I don't want to say which school I'm from , but it's selective.

wait i think i got it , ill post it up when im done lol

expect to find 1 circle geometry question on your paper..

there always is one (might be in another question totally unrelated to geometry until like Q iv)
