Best ResponseYou've already chosen the best response.0part a) just look for graph that matches y=5 sin(x+pi) let's try to draw a graph here. the amp=5 the period=2pi the phase shift is pi can you graph y=5sin(x+pi)?

Best ResponseYou've already chosen the best response.0@freckles so the answer to prt a of the question is answer choice "A"

Best ResponseYou've already chosen the best response.0yes that looks good you can also plug in numbers like 0 and pi/2 and pi and so on to help you pick out the right one

Best ResponseYou've already chosen the best response.0what are the xintercepts of y=5sin(x+pi) in that graph

Best ResponseYou've already chosen the best response.0I dont know what the x intercepts are

Best ResponseYou've already chosen the best response.0do you know hot solve sin(x+pi)=0?

freckles

Best ResponseYou've already chosen the best response.0that will give you the xintercepts if it isn't clear from the graph A

Best ResponseYou've already chosen the best response.0so that is answer choice C

Best ResponseYou've already chosen the best response.0dw:1438062133167:dw hmmm... you should know that sin(2pi+pi)=0 and sin(pi+pi)=0 and sin(0+pi)=0 and sin(pi+pi)=0 and sin(2pi+pi)=0 and sin(3pi+pi)=0

Best ResponseYou've already chosen the best response.0dw:1438062355237:dw this is what the graph should look like if it is not clear where the max values are 5 and the min values are 5

Best ResponseYou've already chosen the best response.0the xintercepts is where the graph touches the xaxis

Best ResponseYou've already chosen the best response.0let's look at graphing y=5csc(x+pi) not recall csc and sin are reciprocals of each other so sin(x+pi) will be reciprocal value of csc(x+pi) for x if sin is 0 then csc is what?

freckles

Best ResponseYou've already chosen the best response.0the only number that doesn't have a reciprocal is 0 right?

Best ResponseYou've already chosen the best response.0so when sin is 0 you have a vertical asymptote for csc

Best ResponseYou've already chosen the best response.0but say sin is 1 then csc is ?

freckles

Best ResponseYou've already chosen the best response.0remember sin and csc are reciprocal functions

freckles

Best ResponseYou've already chosen the best response.0right and 5(1)=5 so both sin and csc will share the following common points dw:1438062820709:dw

Best ResponseYou've already chosen the best response.0we also know if sin is 1 then csc is 1 so we know that the graph will also share dw:1438062857511:dw

Best ResponseYou've already chosen the best response.0now just draw the little U things in between the broken lines so that it is getting closer and not touching

Best ResponseYou've already chosen the best response.0ok so those are the relative maximum and minimum points

freckles

Best ResponseYou've already chosen the best response.0the maxes of the sin function are the relative mins of the csc function the mins of the sin function are the relative maxs of the csc function

anonymous

Best ResponseYou've already chosen the best response.0so what are the coordinates of the relative maximum and minimums of the csc function, im sorry im not tryng to get all the answers out of you because there is another problem just like this and I would like to finish this one fast to see if I can do the next one!

Best ResponseYou've already chosen the best response.0so a relative min/max occurs when the graph is turning but the difference is on that turn if the turn point is above all other points on the subinterval then it is a relative max but if the turn point is below all other points on the subinterval then it is a relative min for example dw:1438063333098:dw

Best ResponseYou've already chosen the best response.0the graph I recently drawed you shows the relative min and max of y=5csc(x+pi)

Best ResponseYou've already chosen the best response.0it is the curve that is black the green one was the sin function (well the asymptotes are also in green but oh well)

Best ResponseYou've already chosen the best response.0the y coordinates should be clear

freckles

Best ResponseYou've already chosen the best response.0the xcoordinate occur midpoint of the zeros

Best ResponseYou've already chosen the best response.0i think I know the x coordinate for the relative max and min, but i don't know the y coordinate

Best ResponseYou've already chosen the best response.0the y's are the easiest though :p

Best ResponseYou've already chosen the best response.0dw:1438063703129:dw so this graph didn't make any sense?

freckles

Best ResponseYou've already chosen the best response.0like you see the y=5 line that is where the relative mins of y=5csc(x+pi) occur and the y=5 line that is where the relative maxs of y=5csc(x+pi) occur

freckles

Best ResponseYou've already chosen the best response.0any point laying on the y=5 line has ycoordinate 5 any point laying on the y=5 line has ycoordinate 5
