WebThe tangent function has period π. f(x) = Atan(Bx − C) + D is a tangent with vertical and/or horizontal stretch/compression and shift. The cotangent function has period π and vertical asymptotes at 0, ± π, ± 2π ,.... The range of cotangent is ( − ∞, ∞), and the function is decreasing at each point in its range. Web首先说cot. 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. 其次是sec,它叫正割. 类似地,cos和sec互为倒数,直角三角形里是斜边/邻边. 这里我多说一句,我建议大家学一下sec的读音 ...
