Mathematics Education Trigonometric graphs lesson 4 – Calculating the period / horizontal dilation By Magic Monk on Monday, October 29, 2018 In this lesson we talk about how you can adjust the period of a trigonometric function by multiplying the input by a factor. E.g. y=sin(kx) would have a period of 360/k (in degrees) or 2pi/k (in radians). education mathematics steemiteducation steempress steemstem Previous Post Next Post Related Posts Mathematics Education Vector applications question – Elastic collision, momentum, and kinetic energy Mathematics Education Vectors lesson 21 – Basic vector operations in Geogebra Mathematics Education Vectors lesson 20 – drawing vectors in Geogebra
