hi,

i need to draw these on to a graph:

1. Y= cosx

2. Y= cosx+1

3. Y= cos(x+30)

i can do 1 and i think i have done number 2 correct but i can't do number 3.

here is what i have done for number 1 and 2, i have had a go at what i think number 3 would be:

i have labled them on the side also.

i think numbers 1 and 2 are correct but if they aren't please let me know and mainly is number 3 correct??

thanks!!!!!
