Answer 3

you know to plot Cosx?

Answer 4

no

Answer 5

find the minimum and maximum of 3 cos x , [0,2π

Answer 6

you know the maximum and minimum value of cos x for any x?

Answer 7

max is 1 min is -1

Answer 8

how? please give the solution please. thank you :)

Answer 9

the angle is varing between 0 to 2pi so if you plug in 0 then cos0 = 1 and you see the angle goes up to pi/2 then value of cosine is decreasing until it reaches x=pi

Answer 10

so it is repeated in all angle...

Answer 11

i need the solution not the graph

Answer 12

that is the solution...

Answer 13

ok, thank you
