Hmm..rare to get asked to use a graphing calculator.

allank · Answer

What you want to do is to make t the subject of this equation, then graph t(theta) with 0<=theta<=2pi

allank · Answer

Whoops, lemme rephrase that

Umm, so basically what I need is the answer and as much work as possible (im not sure how much work I can show if I use the graphing calculator)

What am I supposed to do?

allank · Answer

Alright, we have cos 2t = 3/7

allank · Answer

Using a graphing calculator we can compute arccos(3/7)=1.128

allank · Answer

Which in radians is about 0.36 radians.
