Question

sin 2z =0.23 -180≤ z ≤180. find the value of z to 1 decimal point

Answer 1

Are you allowed to use a calculator?

Answer 2

yes

Answer 3

You could try this:

\[\large \sin 2 z=\dfrac{2\tan z}{1+\tan^2 z}\]

You get a quadratic in z. Solve for it.

Or

simply take sin inverse on both sides.

Answer 4

okay..sin 0.23=13.3 and the question wants angle if it rotates -180 and 180..

Answer 5

Actually the answer you get will be in range:
