Let's take a look at the four ways we can transform a tangent function and graph. A changes the amplitude, or how steep the graph is along the y axis. B changes the period, or how wide one pattern of the graph is. C changes the phase shift, or how the graph is shifted to the left or the right. D controls the vertical shift, or how the graph is shifted up or down.
Wear your corrective lenses to see where you are going or it won't be just eyes hurt. Floaters, the little bits of scar tissue in the jelly of the eye that lead or lag behind the motion of the eye thus drift or float are made worse in excessive eye rubbing or worse can lead to retinal tears or detachment. Avoid this practice. Treat the itching if that is what the problem is in the first place.
retinal detachment. RETINAL DETACHMENT. Separation of the inner sensory layer of the retina from the outer pigment epithelium. It is usually caused by a hole or break in the inner sensory layer that permits fluid from the vitreous to leak under the retina and lift off its innermost layer.Causes include trauma and any disease that causes retinopathy, such as diabetes or sickle cell disease.etinal detachment occurs most often as a result of degenerative changes in the peripheral retina and vitreous body, which produce holes or tears in the retina that can range from minute breaks no larger than 0.1 mm to extensive holes that extend over the entire fundus.
