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??
