We can graph \(y=\cot x\) by observing the graph of the tangent function because these two functions are reciprocals of one another. See Figure \(\PageIndex{8}\). Where the graph of the tangent function decreases, the graph of the cotangent function increases.

Set the argument in cot(x) cot (x) equal to πn π n to find where the expression is undefined. The domain is all values of x x that make the expression defined. The range is the set of all valid y y values. Use the graph to find the range. Determine the domain and range.

We know the sketch for y = cos x and we can easily derive the sketch for y = sec x, by finding the reciprocal of each y-value. (That is, finding `1/y` for each value of y on the curve `y = cos x`.) For example (angles are in radians):

我估计部分高中生应该学过cot。 它叫 余切，和tan互为倒数。 所以，在直角三角形里，tan是对边/邻边，那cot自然是邻边/对边了. 注意啊是画图，我觉得初学时应该自己探究着画。 一方面，亲自动手和直接看图像肯定是不一样的；另一方面，这个过程一定程度上也锻炼了探究能力. 如果把图放大，你会感觉y=secx的每个单元（也就是每半个周期）像啥？ 是不是有点像大铲子。 诶， …

The cotangent is one of the trigonometric ratios and is defined as cot x = (adjacent side)/(opposite side) for any angle x between the base and hypotenuse in a right-angled triangle. What are Cotangent Formulas?

反余切函数（反三角函数之一）为余切函数y=cotx（x∈ [0,π]）的反函数，记作y=arccotx或coty=x（x∈R）。 由原函数的图像和它的反函数的图像关于一三象限角平分线对称可知余切函数的图像和反余切函数的图像也关于一三象限角平分线对称。 y=cotx的图像及其反函数的图像y=cotx的图像：y=cotx反函数的图像：在直角三角形中，某锐角的相邻直角边和相对直角边的比，叫做 …

Apr 18, 2024 · y = secx, 即1cosx\frac{1}{cosx}函数的倒数不改变奇偶性质。借助cosx的图像：当cox趋近于0时，secx是无穷大。y = cscx, 即$\frac{1}{sinx}再来思考反函数。其实想通以后，反
