Question

what is the y-value of cos(x) if x=0

Answer 1

is this a long winded way of asking what \(\cos(0)\) is?

Answer 2

hey i asked you to think about a graph..and also gave you a hint..no point repeating it

Answer 3

just think about the values of x where the graph of cos(x) intersects the y axis..i will give you one. 90deg is one of the many

Answer 4

lol how can you graph if you don't know what \(\cos(0)\) is??

Answer 5

find the angle 0 on the last page of the attached cheat sheet
then look at the ordered pairs on the unit circle
the first coordinate is cosine, the second coordinate is sine

Answer 6

hey satellite its easier to think..i personally find it easier coz i divide the graph in muliple fragments each 90deg

Answer 7

but for that you ought to have an idea of cos sketch

Answer 8

it is easier to think if you know what you are doing for sure, but there is no way to graph cosine without knowing its values to begin with
first you know the values, then you can graph

Answer 9

is it -1

Answer 10

well the values can only be 0,1,-1 so its not too difficult to remember for sure

Answer 11

hey trevor it certainly isnt

Answer 12

just put that in calculator and find it out..you should get +1

Answer 13

gotcha
