Question

medal
If sine of x equals 1 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences.

Answer 1

For what angle x does sin(x) = 1/2 ?

Answer 2

It's a very commonly known value. Once you have the angle you will have all your answers.

Answer 3

Hint: I would suggest you memorize what the sine and cosine of 30,45 and 60 degrees is because you'll see them a lot in exercises and tests.

Answer 4

i think -30

Answer 5

cos(x) = sqrt 3/2

Answer 6

\[\sin x=\frac{ 1 }{ 2 }\]
\[\sin ^2x+\cos ^2x=1,\cos ^2x=\frac{ 3 }{ 4 }\]
\[\cos x=\pm \frac{ \sqrt{3} }{ 2 }\]
\[\tan x=\pm ?\]

Answer 7

is there a formula for tan

Answer 8

\[tanx=\frac{ \sin x }{ \cos x }\]

Answer 9

so 3/4/sqrt 3/2

Answer 10

.61

Answer 11

no
\[\pm \frac{ \frac{ 1 }{ 2 } }{ \frac{ \sqrt{3} }{ 2 } }=\pm \frac{ 1 }{ \sqrt{3} }=\pm \frac{ \sqrt{3} }{ 3 } = \pm \frac{ 1.732 }{ 3 }=?\]

Answer 12
