I'm dealing with sin Theta tan Theta = 1/2tan Theta…I tried subtracting 1/2tan Theta from each side, but then I wouldn't be able to factor it out. I tried using the Quotient Identity of tan Theta, but that doesn't make sense cause 1/2tan Theta is still there on the right side of the equation when it needs to be 0. I tried subtracting sin Theta from both sides so I can factor out the left side of the equation but then the right side will never be 0. I can't. I'm tired

I am told again and again that it's illegal to divide by zero.
Then I'm told that I can factorize a rational expression by using the zero product property on numerator and the denominator.

How does this contradiction work?

I just got an assignment where there are no 0's in the equation. For example: _x(squared) – _x = _ – _x. Is this a fluke??
