2018年1月16日 · Lets first analyse the function for the period [-π/2,π/2] tan (-x)=-tanx thus Odd Function Some specific points tan (0)=0, tan (π/2)=infinity, tan (-π/2)= - infinity Lets see the graph of tanx lies above or below y=x graph {x [-20.12, 19.88, -9.32, 10.68]} Consider the function tanx - x Differentiating it w.r.t to x sec2x −1 since sec2x −1> 0 It is an increasing function at x=0 ,tan x ...

2015年9月21日 · graph {tan x [-10, 10, -5, 5]} The number of lines you have to draw depends on the domain provided. If the domain is not specifically provided, you will have to draw them all (that's what the function does). If you're doing it by hand, I would first trace some vertical construction lines (asymptotic lines) at π 2, − π 2, etc..., where tanx is not defined. Then I would plot a few points and ...

2015年2月28日 · The concepts of odd and even apply only to integers . Except for a very few special angles the values of the sine, cosine , and tangent functions are non-integer .

2015年1月29日 · The period of y=tanx is pi. In fact: graph {tanx [-10, 10, -5, 5]}. The "fundamental" branch is in (-pi/2,pi/2).

2018年4月30日 · Consider the standard graph of tanx below. graph {tanx [-10, 10, -5, 5]} y has this standard graph scaled by 1 2 as below graph {1/2 (tanx) [-10, 10, -5, 5]}

2015年10月28日 · When a coefficient is present in the function like in this case is 2, the transformation rule states that you should multiply the result of tanx by 2. In the case of tanx When you did tan45, the outcome was 1. Now as the function is 2tanx, the out come is 1*2 i.e 2. SO the graph is, you multiply the values of y of tan x with 2 and it becomes ; graph {2tanx [-12.65, 12.65, -6.32, 6.33]} For ...

2015年4月17日 · The period of tan x is pi. You can see it on the graph: graph {tanx [-10, 10, -5, 5]} Example: tan pi/4 and tan (pi/4 + pi) have the same value (1).

2017年11月19日 · See below. The graph of y=tan3x is the graph of y=tanx with a horizontal compression by a factor of 1/3 The period of tanx is pi, so the period of tan3x is: 1/3*pi=pi/3 Graphs of y=tan3x and y=tanx

2015年10月10日 · Domain: (theta|theta!=kpi/2, where k is an odd integer) Range: (-oo,oo) Remember that tan=sin/cos therefore, you will have a vertical asymptope whenever cos=0. Cos=0 every odd multiple of pi/2. If you plug y=tan (x) into a graphing calculator you will see that the ends of each section continue on infinitely along the y-axis.

2018年6月11日 · Above is y = tan(x − π 2) If you focus on (0,0) in the first graph, you will notice that in y = tan(x − π 2), it has shifted to the right by π 2 units or approximately 1.57 units to the right.
