Question

Помогите решить пожалуйста

Answer 1

$1) \ Sin^{2}\dfrac{\pi }{3} +Cos^{2}\dfrac{\pi }{6} =\Big(\dfrac{\sqrt{3} }{2}\Big)^{2}+\Big(\dfrac{\sqrt{3} }{2}\Big)^{2}=\dfrac{3}{4}+\dfrac{3}{4}=\dfrac{6}{4}=\dfrac{3}{2}=\boxed{1,5}\\\\\\2) \ Cos^{2}\dfrac{\pi }{3} +Sin^{2}\dfrac{\pi }{6} =\Big(\dfrac{1}{2} \Big)^{2}+\Big(\dfrac{1}{2} \Big)^{2}=\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}=\dfrac{1}{2}=\boxed{0,5}$
