Question

Find the exact value of the expression.
cos(arcsin1/2+arccotroot 3/3)

Answer 1

arcsin 1/2= ?
can u evaluate that?

Answer 2

means \[\sin^{-1} (1/2) \]

Answer 3

im lost

Answer 4

for what angle is the value of sin 1/2 = ?

Answer 5

60 degrees

Answer 6

nopes, sin 60 = root 3/2
sin 30 = 1/2

Answer 7

so arcsin 1/2 = 30 degrees, ok ?

Answer 8

ok

Answer 9

and for what angle is cot x = root 3/3 or 1/ root 3 ?

Answer 10

30?

Answer 11

cot 30 - root 3, cot 60 = 1/root 3

Answer 12

so u have arccotroot 3/3 = 60
so what is the value of arcsin1/2+arccotroot 3/3 = ?

Answer 13

@Zekarias arcsin 1/2 = 60 ?

Answer 14

arcsin1/2+arccotroot 3/3 = 30+60= ?

Answer 15

u lost me

Answer 16

u clear with arcsin 1/2 = 30 ?

Answer 17

because sin 30 = 1/2

Answer 18

okay

Answer 19

arccotroot 3/3 = 60
because
cot 60 =1/ (root 3) = root 3/3

Answer 20

so arcsin1/2+arccotroot 3/3 = 30+60= ?

Answer 21

90 ?

Answer 22

yeah, clear till here ?

Answer 23

yup

Answer 24

cos(arcsin1/2+arccotroot 3/3)
=cos 90 = ?

Answer 25

0

Answer 26

that is correct and is the final answer :)

Answer 27

ohh ok thank you

Answer 28

welcome ^_^
