The standard deduction is a dollar amount that reduces the amount of income on which you are taxed. In general, the standard deduction is adjusted each year for inflation and varies according to your filing status, whether you are 65 or older and/or blind, and whether another taxpayer can claim you as a dependent.ou are allowed an additional deduction for blindness if you are blind on the last day of the tax year. For example, a single taxpayer who is age 65 and blind would be entitled to a basic standard deduction and an additional standard deduction equal to the sum of the additional amounts for both age and blindness.
exists and is an alternate of . Making the world better, one answer at a time. The physics definition of period is the duration of one complete cycle of a wave or oscillation. The physics definition of period is the duration of one complete cycle of a wave or oscillation.
The amplitude of the graph of y = a cos bx is the amount by which it varies above and below the x-axis. Amplitude = | a |. The period of a cosine function is the length of the shortest interval on the x-axis over which the graph repeats.Period =. Example : Sketch the graphs of y = cos x and y = 2 cos x. Compare the graphs. For the function y = 2 cos x, the graph has an amplitude 2.Since b = 1, the graph has a period of. Thus, it cycles once from 0 to with one maximum of 2, and one minimum of â2. Observe the graphs of y = cos x and y = 2 cos x.he amplitude of the graph of y = a cos bx is the amount by which it varies above and below the x-axis. Amplitude = | a |. The period of a cosine function is the length of the shortest interval on the x-axis over which the graph repeats.
