Find the value of 4sin square 60degree-cos degree 45degree *tan square 30 degree +sinsquare 0degree

Answer 1

$4 \sin(60) {}^{2} - \cos(45 {}^{} ) {}^{2} \times \tan(30) {}^{2} + \sin(0) {}^{2} \\ 4 \times ( \frac{ \sqrt{3} }{2} ) {}^{2} - ( \frac{1}{ \sqrt{2} } ) {}^{2} \times ( \frac{1}{ \sqrt{3} }) - 0 {}^{2} \\ 4 \times \frac{3}{4} - \frac{1}{2} \times \frac{1}{3} - 0 \\ 3 - \frac{1}{2} \times \frac{1}{3} \\ 3 - \frac{1}{6} \\ \frac{3 \times 6}{1 \times 6} \\ \frac{18}{6} - \frac{1}{6} \\ \frac{17}{6}$
