TO evaluate: 3 sin -1 (1/root 2) + 2 cos -1 (root3/2) + cos-1(0)
3 space sin to the power of negative 1 end exponent open parentheses fraction numerator 1 over denominator square root of 2 end fraction close parentheses plus 2 cos to the power of negative 1 end exponent open parentheses fraction numerator square root of 3 over denominator 2 end fraction close parentheses plus cos to the power of negative 1 end exponent open parentheses 0 close parentheses equals 3 cross times straight pi over 4 plus 2 cross times straight pi over 6 plus straight pi over 2 equals fraction numerator 3 straight pi over denominator 4 end fraction plus straight pi over 3 plus straight pi over 2 equals fraction numerator 9 straight pi plus 4 straight pi plus 6 straight pi over denominator 12 end fraction equals fraction numerator 19 straight pi over denominator 12 end fraction
