Question

find the value of theta for 0 10 years ago

Answer 1

no

can you solve for x in
\[ x^3 = -\frac{1}{8} \]?

Answer 2

2^-3

Answer 3

you need to review cube roots

x= -½ (because -½ * -½ * -½ = -⅛

that means in your problem
sin theta= -½

now find the "inverse sin"

but you (should) know sin 30 deg = ½

Answer 4

in case you did not know
\[ \sin^3 \theta \text{ means } ( \sin \theta)^3 \]

Answer 5

I always associate "sin" with "y" in the unit circle

-½ means the y value is negative. there are two quadrants with a negative y
