Okay I think I have got Trigonometry down

gentillabdulla

Ok I have been using the Khan academy lessons, currently working on the final parts of calculus on the exercise dashboard, and I have previously finished trigonometry.

Now I want to test my knowledge through questions on trigonometry that you guys can give me.(Be it word problems or whatever.)

I am saying this because I need to know my limits and would love a good mental workout.

SO anyone who has read this I ask you to please give me trig questions. Come at me NOW!:P

You could go on to www.examinations.ie and do some of the Leaving cert trigonometry questions. Trigonometry is examined in questions 4 and 5 of paper 2 at higher level.

What level of questions? It's possible to make them more or less arbitrarily hard. Can we ask for identities involving derivatives?

Find a method of calculating [latex] \sin\left(\frac{\pi}{2^n}\right)[/latex] for arbitrary n.

Fairly simple.

You can use the ones at the khan academy exercise dashboard as a reference.

Here's the link to that....

And the second one is trig 2

These are basically the only ones I am used to, but I have done the various trig identities and others.

This is included in one of the 3 last trigonometric videos that I am watching.(When I am fully prepared I will give my reply!
