Solve for exactly (0, 2 pi) . cos theta + 2 sin(2 theta) = sin (2 theta) Substitute r = \sin \theta into x = r \cos \theta and y = r \sin \theta to find x and y in terms of the parameter \theta. Then...
However, after a rotation by an angle displaystylepi, the points B and C already return to their original position, so that the tangent function and the cotangent function have a fundamental period ...
