Trigonometry - Negative Angles & Some important Tricks! (Grade 11 Maths)

[@lisaplaatjies7066]

Why is tan still negative if All the ratios are postive in the first quadrant?

[@siphesihledlomo8458]

Negative angle sits in Q4, only Cos is positive there

Wow. Excellent explanation. I love the little notes you provided, will come in handy during the exam. God bless you, dear sir.

For the last question why did he keep the -tan if in that quadrant ALL ratios are positive?

[@nadiagovender7277]

The negative comes from when he factorized it out in the beginning so it was not affected by the bracket.That's how I understand it. I could be wrong though xx
