2017年1月20日 · To draw the graph of this function you kave to draw the graph of y=cosx graph{cosx [-7, 7, -2, 2]} and translate it by a vector [pi;0] (i.e. move the graph pi units to the …

2014年10月21日 · First, the graph of y=cos(x-pi/2) will have some characteristics of the regular cosine function. I also use a general form for trig functions: y = a cos(b ( x - c)) + d where |a| = …

2015年5月21日 · Since y = cos^-1 x, then x = cos y. So, this graph is a rotation of the cosine wave by 90 degrees. Or at least part of it. Technically if cos^-1 of a number gave the output 'n', then …

2017年7月15日 · Remember the cos function has the following points: (0,1),(90,0),(180,-1),(270,0),(360,1) But because it 2x the period is shortened.

2015年7月1日 · This value of the period tells you that this is not the normal cosine but it is "squeezed" to fit an entire oscillation between 0 and pi instead of between 0 and 2pi as the …

2016年9月2日 · See explanation below graph{cos(pi*x) [-5, 5, -2, 2]} Graph of function y=f(x), by definition, is a set of all points (A,B) on the coordinate plane that satisfy the equation B=f(A). …

2014年10月6日 · y=|A|cos(x), where |A| is the amplitude. y=1*cos(x) y=cos(x) The range for this trig problem is related to the amplitude. The amplitude for this function is 1. This function will …

2018年6月10日 · there's no direct approach (as far as I know) we have cosx1/x plot cosx graph{cosx [-10, 10, -5, 5]} now plot1/x graph{1/x [-10, 10, -5, 5]} cosx/x is hybrid of both notice …

2018年1月29日 · #color(blue)(y = cos x)# Then we will graph. #color(blue)(y = - cos x)# Then we will graph. #color(blue)(y = cos 2x)# Then we will graph. #color(blue)(y = -cos 2x)# Next, we …

2016年3月24日 · The graph is oscillatory between y = x and y=-x. The expanding waves meet x-axis at origin and x=+-(2n-1)pi/2, n =1, 2, 3, 4, . |y|=|x cos x|<=|x| If (x, y) is on the ...
