I am having a few problems solving this one.
"Show that the area A of an isoceles triangle is... A=a^2sinθcosθ, where a is the length of one of the two equal sides and θ is the measure of one of the two equal angles..
,,,/..\
a/....\a
,/......\
/θ...θ \
---------
(thats the diagram they show, and the periods and commas are only to help it maintain shape in yahoo)....
I'm not completely helpless, we just started this chapter and I kind of understand what you have to do and I know all 4 angles should be 60degrees, but it doesnt solve right when I do it.
An english translation would be helpful :/... thanks!
