In learner-centred methods, the teacher/instructor is both a teacher and a learner at the same time. In the words of Lawrence Stenhouse, the teacher plays a dual role as a learner as well âso that in his classroom extends rather than constricts his intellectual horizonsâ.
Two-point perspective has one set of lines parallel to the picture plane and two sets oblique to it. Parallel lines oblique to the picture plane converge to a vanishing point, which means that this set-up will require two vanishing points. Walls in 2-point perspective, converging toward two vanishing points.
If the power series only converges for then the radius of convergence is and the interval of convergence is. Likewise if the power series converges for every x the radius of convergence is and interval of convergence is. Letâs work one more example.f the power series only converges for then the radius of convergence is and the interval of convergence is.
