Trig problem
Use a calculator to decide whether the statement (sin^2 theta) divided by (1+cos theta) is equal to (1-cos theta) is an identity. I'm pretty sure that its not a property (but if it is I have to show which one) but I also have to provide a counter example if its not does anybody have an idea on how this is done???

Thanks
