Can we get any possible details? I think maybe you are confusing some more difficult coordinate geometry with trigonometry. I beleive it is nearly impossible to do trigonometric calculations without a calculator.
Trigonometry was beyond the scope of the ETS version of the test. Sounds like the new GMAT is harder.
I'm confused about this too. The test was previously administered
by ETS and now Pearson. GMAC has always written the test, correct?
Besides, since OG11
is published by GMAC, and is the most recent version, and has no mention of any trigonometry, don't you think it would be unfair to place that in the test without listing it as one of the objectives?
