what is the value of sin²(α)+sin²(β)+sin²(γ)? why? ?
[This question is in regards to the topic of vectors, alpha, beta, and gamma referring to the direction vectors ]
* direction angles

It was 0 but I don't remember.
Why because you were solving by every sine.
Sin^2(a) = Sin^2(180-b-g)
And then you can use the identities.
It should give you 0 but I don't remember. Try to solve it.

What do you mean why?
