Mabelen Posted December 6, 2010 Share Posted December 6, 2010 Do you know of any good websites/video clips I can find on the Internet where this is explained? My 14 yo is strugling right now with a particular tangent ratio word problem. I am wondering if any of you can direct us to a good free online resource. I looked at Khan Academy but I coulnd't work out which of the videos deals with this particular concept. Thank you so much in advance.

Tullia Posted December 6, 2010 Share Posted December 6, 2010 (edited) You might try this one which my son used quite a bit: http://www.mathvids.com/ ETA: There is a charge for some "premium" services, but my son usually found what he needed in the free section.
