Question 1208450
.
If cot(theta) is undefined, and cos(theta) < 0, what are the values 
of the six trigonometric functions?
~~~~~~~~~~~~~~~~~~


<pre>
Then  theta = {{{pi}}},  or 180 degrees.


sin(theta) = 0


cos(theta) = -1


tan(theta) = 0


cot(theta) is undefined


sec(theta) is -1


csc(theta)  is undefined.

It's like asking about the multiplication table.
A good student's answers should bounce off like ping-pong balls off a wall.
