Answer 1

Ответ:

y₁=20; y₂=-36; y₃=-20; y₄=81

Объяснение:

y₁=20sin(1·π/2)+(1+5)²cos(1·π/2)=20sin(π/2)+6²cos(π/2)=20·1+36·0=20

y₂=20sin(2·π/2)+(2+5)²cos(2·π/2)=20sinπ+7²cosπ=20·0+36·(-1)=-36

y₃=20sin(3·π/2)+(3+5)²cos(3·π/2)=20sin(3π/2)+8²cos(3π/2)=20·(-1)+64·0=-20

y₄=20sin(4·π/2)+(4+5)²cos(4·π/2)=20sin(2π)+9²cos(2π)=20·0+81·1=81
