Trigonometric Graph Transformations (Enlargements, Reflections & Translations) | GCSE Maths

In this video we go through how to apply graphs transformations to trigonometric graphs: enlargements, reflections and translations. Including applying two transformations to the same question. If you want to cover what the different types of transformations are then check out the part 1 video listed below and if you want to see how transformations are applied to non-trigonometric graphs then check out the part 2 video. This is a HIGHER TIER topic only.
