Can someone explain sin/cos graphs and their reflections?
I was doing a question which asked the transformations to get from 6sin(PiX/2) Domain:(0 to 4 including) to the graph of 6cos(PiX/2) Domain: (-3 to 1 including) and the answer was a reflection in the x and translation 3, but I was just thinking about a reflection in the y and shifting it then?

And i checked my textbook it said that a reflection in the x and y is the same thing for a sin graph and a reflection in the x for a cos graph affects it but a reflection in the y doesn't...So i tried it on my CAS but a reflection in the y axis on a cos graph does work?

...will you still get marks for methods if you do working out right but the answer is wrong?
