Sorry sir I can start he the graph vertically but I am finding it difficult to squash it still have you any way to help sorry and also do you normally only mark in your points upto 2pie or would degrees be okay? Sorry 📈📉

Either radians or degrees are fine.
Regarding squashing the graph - it's about working out the period or length of the function e.g. for sin and cos:
- if the angle is x the period is 360
- if the angle is ax the period is 360/a
- if the angle is x/a the period is 360a
I'll find a video that explains this and put it in the blog.
