Two different tangent lines intersect the circle at points D and E. Those same tangent lines intersect each other outside the circle at point F, forming an acute angle of 50 degrees. If a chord is drawn between D and E, what is its length?ccanoncWed, 20 Oct 2010 12:18:26 +0200https://ask.sagemath.org/question/7737/GRE Math Subject Test Sample Question #3https://ask.sagemath.org/question/7736/gre-math-subject-test-sample-question-3/How many dimensions can be present in the intersection of A and B, for A,B both 2D subspaces of R^4?ccanoncWed, 20 Oct 2010 12:02:34 +0200https://ask.sagemath.org/question/7736/SAT Math Level 2 Subject Test Sample Question #19https://ask.sagemath.org/question/7733/sat-math-level-2-subject-test-sample-question-19/What is the limit of $f(x)$ as $x$ approaches infinity, for $f(x) = (4*3 + 3x) / (-12 + 2x)$ ?ccanoncMon, 18 Oct 2010 15:28:00 +0200https://ask.sagemath.org/question/7733/GRE Math Subject Test Sample Question #2https://ask.sagemath.org/question/7496/gre-math-subject-test-sample-question-2/Find the linear equation for the line which touches the following curve only once when x = 0, curve: y - x = e^x
