Graph the function in the interval from 0 to 2pi.
y = 2 cos(theta+pi/6)+2
How do I graph this? This is a sample question. I'm preparing for my final and I really need help

Best ResponseYou've already chosen the best response.0I'm new to Trignometric Graphing myself I tried around with the trignometric graphing calculator myself and I got the answer as the 2nd graph I'm trying to figure out how

Best ResponseYou've already chosen the best response.0@girlygirl12151 But how did you get that? I would like to know how to graph problems like these in the future

Best ResponseYou've already chosen the best response.0Ok first of all the c in the equation which is the 2 is causing vertical shift

Best ResponseYou've already chosen the best response.0the pi/6 is the horizontal shift. It's moving the graph by 30° to the left (if the radian is positive)

Best ResponseYou've already chosen the best response.0@nopen okay.. i don't understand much of that, but I understand a little. At least i know what i need to go deeper into studying

Best ResponseYou've already chosen the best response.0@nopen do you know how i'd tell if the radian is positive. (this might be a dumb question)

Best ResponseYou've already chosen the best response.0and the 2 that you see that multiplies with the whole equation is the stretch factor, the larger that number, the more the amplitude will get stretched. here plot the graph in this link: https://illuminations.nctm.org/Activity.aspx?id=3589

Best ResponseYou've already chosen the best response.0it's simply any number if it's have +pi/whatever number that's positive radian and if it's negative it will have a negative sign

Best ResponseYou've already chosen the best response.0I can tell you one thing though the last graph is absolutely out of the option do you know why?

Best ResponseYou've already chosen the best response.0@nopen Is it because its over the line?

Best ResponseYou've already chosen the best response.0Nope it's because your equation is have the the +2 y = 2 cos(theta+pi/6)+2 < this 2 it means it's have a vertical shift upwards by 2 units

Best ResponseYou've already chosen the best response.0@nopen and it's under the 2 with the starting point at 4

Best ResponseYou've already chosen the best response.0the problem says 02pi so that makes sense

Best ResponseYou've already chosen the best response.0@nopen I have to get ready to go to work. Thank you for the link to the graph calculator and for your help. Have a great day!
