For the following equation, graph y = f1(x) and y = f2(x) on the same screen on your calculator. From the graphs, make a conjecture as to whether the equation is an identity. If so, prove your conjecture.cos 2x = sin 2x tan x
What will be an ideal response?

Determine whether the pairs of lines are parallel, intersect at a single point, or are skew. If the lines are parallel, determine whether they are the same line (and thus intersect at all points). If the lines intersect at a single point, determine the point of intersection.r = (3, 1, 4) + t(-1, 6, -2); R = (-6, 55, -14) + t(5, -30, 10)
A. The lines intersect at a single point, 
.
B. The lines are parallel, distinct lines.
C. The lines are the same line.
D. The lines are skew.
