Question

experimentx · Answer

what is r and what is theta??

anonymous · Answer

I think he means like on the unit circle r the radius. that is just the area formula I believe listed in the back of most trig books

chrisplusian · Answer

yes that is correct but I can't find it in the back of my trig book. I always thought of  the area of a triangle as half times base times hieghth.

anonymous · Answer

It is but this is another way!

anonymous · Answer

they usually won't list the h pretty ever in trig.

anonymous · Answer
