Question

find the value of sin 1000​

Answer 1

Answer:

-0.9848

The value of sin 1000° is -0.9848 (approx).

Answer 2

I’m going to assume that you meant 1000 degrees and not radians. We have that since sine is periodic every 360 degrees, sin(1000) = sin(-80) = -sin(80).

From there, you could use 1/3-angle formulae (they’re not fun) to calculate it in terms of sin(240), or at this point you can use a calculator to get -0.9848.
