log3 x - log3(x-3) = 2

I got 1 as an answer. Is this correct?

2) Find the cotangent of the base angle of an isosceles right triangle.

sqrt3 / 2. Is this correct?

**FredR**, Wednesday, March 10, 2010 at 6:29pm1) it is not correct. The second term would be log3(-2) and you can't take the log of a negative number.

2) it is not correct. The base angle would be 45 degrees, so the cotangent would be 1.
