Cosθ = −√2 / 3, where π ≤ θ ≤ 3π / 2 .
tanβ = 4/3 , where 0 ≤ β ≤ π / 2 .
What is the exact value of sin(θ+β) ?
Enter your answer, as a fraction in simplified form.
sin(θ+β) =
I tried & I got -√7/5 - 4√2/15.
I'm pretty sure it's wrong, because it asks for a fraction in simplified form, but if someone could help that would be great.. thank you:)
