Best ResponseYou've already chosen the best response.1ok, so you know:\[\sec(\theta)=\frac{1}{\cos(\theta)}\]which means you now know:\[\cos(\theta)=\frac{1}{\sec(\theta)}=\frac{1}{5}\]

Best ResponseYou've already chosen the best response.0great so now we know cos(theta). but i dont see how that helps us find cot(90theta)

Best ResponseYou've already chosen the best response.1so if you now use the Pythagoras theorem to work out x, then you should be able to work out the answer to your question.

Best ResponseYou've already chosen the best response.1sorry, I meant \(\cot(90\theta)\)

Best ResponseYou've already chosen the best response.1what you gave was the value of \(\cot(\theta)\), what would \(\cot(90\theta)\) be?

Best ResponseYou've already chosen the best response.0ohh.. ok i think i get it. i wasnt visualizing it, my college prof. is a fluttering idiot pardod my french, and he's taking vicadon, and he doesnt explain anything. in fact so far he hasnt given us any notes.. he's just went through examples of things and walked us through them. but i appreciate the help
