$\qquad❖ \: \sf \: \sin {}^{4} ( \alpha) + 2 \sin {}^{2} ( \alpha) \cos {}^{2} ( \alpha) + { \cos {}^{4} ( \alpha) }^{}$

$\qquad❖ \: \sf \:( \sin {}^{2} ( \alpha) ) {}^{2} + 2( \sin {}^{2} ( \alpha))( \cos {}^{2} ( \alpha)) + {( \cos {}^{2} ( \alpha)) }^{}$

( use identity a² + 2ab + b² = (a + b)² )

$\qquad❖ \: \sf \:( {\sin {}^{2}( { \alpha}) + \cos {}^{2} ( \alpha)) }^{2}$

( sin² x + cos ² x = 1 )

$\qquad❖ \: \sf \: {1}^{2}$

$\qquad❖ \: \sf \: {1}^{}$

Value of that expression is 1

Use the distance formula!

d = square root of (x2-x1)^2 + (y2-y1)^2
