Question

Sooo, I need help...again...
let f(x)= sin(x)
f((2π)/3)
*do please show steps...I will appreciate it)

Answer 1

okay so when it says f((2π)/3)), it wants you to put (2π)/3 where x is in the function

so the function is sin(x), so let's put (2π)/3 where x is

f((2π)/3) = sin((2π)/3)

Answer 2

so what is the value of sin((2π)/3)?

take a look at the unit circle

Answer 3

so its 120 degrees? @robz8

Answer 4

yes. 2pi/3*180/pi
2/3*180
2*60
120

Answer 5

yes, is a 120, usually your unit circle would have radians unit alongside too :/

Answer 6

thanks a bunches @Beebe97 & @jdoe0001 !!!!

Answer 7

you wouldn't write the answer in degrees, it should be (√3)/2 radians

Answer 8

No problem
