Taiwanese Journal of Mathematics, Vol. 24, No. 2 (April 2020), pp. 355-376 (22 pages) Let H(𝔻) denote the space of holomorphic functions on the unit disk 𝔻 of ℂ, ψ, φ ∈ H(𝔻), φ(𝔻) ⊂ 𝔻 and n ∈ ℕ ∪ ...

In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. The author ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...
