Answer 1

value of sin degree

Answer 2

@midhun.madhu1987

Answer 3

I am not sure how it can be calculated without using calculator.... or we can have approximation...
eg. sin 30 = 1/2 = 0.5
so sin 23 can be approximated to something around 0.42 etc...
No ideas other than this... :(

Answer 4

we can use formula sin^2x+cos^2x=1

Answer 6

are you trying to do this without a calculator?

What is the topic you are studying ( e.g. trig identities?)

Answer 7

yes

Answer 8

I don't know a neat/quick way as 23 is a prime number and doesn't correspond to any multiples of standard angles.

Here is a link to a very long way to do it for ANY integer angle:

Answer 9

very lengthy way only

Answer 10

can u do that

Answer 11

you can do this

Answer 12

\[\sin23 = \sin(90-67)\]
=\[\cos67\]

Answer 13

okay i try.all help me

Answer 14

sin90cos67-cos90sin67

Answer 15

sin90=1
cos90=0
so its the same as cos67

Answer 16

1.cos67=?

Answer 17

cos67=?

Answer 18

i dont know but i found this on the internet:
\[\cos67 = (\sin 23\Pi)/180\]

Answer 19

which is basically sin 23 sorry

Answer 20

sin is defined as the sum of a series

BUT oyu need to get 23 deg in radians ( so you need a calculator!)

The series is

sin x = x -x^3/3! + x^5/5! - x^7/7!.........

However you need a calculator for this - so not sure where the question leads you ...

Answer 21

k.sin 27 degree
