# c3 transformation of trig graphs watch

Announcements
1. Hi,

Just want to check my understanding on something...

If we have a graph of cosecx, and it is stretched in the y direction scale factor 3, would this have any impact on the way it looks, giving that it carries on forever anyway?

Above the x axis, the minimum points of cosecx (where sin has it's maximum points), would these still be at y=1, for 3cosecx?
2. What is the y coordinate of the first + minimum point of y = cosec(x)
What do you expect to happen if you have y= 3cosec(x) ?

Y coordinate of first + minimum point is 1, when stretched by SF3 in y direction I expect all y values to be multiplied by 3, so the minimum points should be y=3?

I think you may have confused max/min points with max/min values of the function.

Thanks! I worked out the initial points first and then just repeated it within the required range. This gave the right answer. Thanks for your help.
