Find the exact value of sin 15°.

I got square root of 2-squaroot of 3/2

is that correct?

  • Precalculus - ,

    You'd have to get used to being precise with parentheses if you want to do well in maths.

    I got "square root of 2-squaroot of 3/2"
    √2 - √(3/2),
    more or less, which is probably not quite what you mean.

    can be found by the half-angle formula
    which is very similar to your answer less the parentheses.
