Question

arccos0?

Answer 1

1/cos(0)

Answer 2

Answer 3

@tomo is that the asnwer?

Answer 4

?? that doesn't make sense. please reword

Answer 5

the one with tangent?

Answer 6

what is arccos0??

Answer 7

cos(0) = 1.

Answer 8

@tomo

Answer 9

arccos(0)= 90 degrees or pi/2

Answer 10

one second. it is a little different than i first thought it was.

Answer 11

k but plz try to expalin i have test on this toorrow

Answer 12

k what is the answer of the questio with tangent?

Answer 13

Answer 14

Well it's just the inverse of cos(0). Cos(0) =1. The inverse of that switches the values of the sine cosine functions. cos(90) gives you 1. but because remember, sin(0)=0 and sin(90)=1

Answer 15

cos(90) is 0*

Answer 16

and an easy way to remember is: sin is your y axis and cos is your x axis. the inverse of a function is basically switches the x and y. what was y=f(x) is now x=f(y)

Answer 17

k i know that but i have like 5 problems to work on i just want the right answers to it so i can practice

Answer 18

for the test tomorrow

Answer 19

socan u tell me the answer to the tangent one?plz

Answer 20

\[\arcsin-\frac{ \sqrt{3} }{ 2 }\]

Answer 21

and this one plz i have to go emergency plz answe those 2 for me plz

Answer 22

that will be really helpful

Answer 23

-pi/6 and -pi/3 (take a look at the unit circle for the second one)

Answer 24

how did u get -pi/6? i know in the unit cirlce but when i tried all of them tan is y/x then which onw will work?

Answer 26

Let's see. arctan (sqrt3/3) is the same thing as arctan (1/sqrt3) right? and using 30-60-90 triangle, you have this:
