Question

Найдите значение функции y=2sinx+cosx eсли x =p/2

Answer 1

y=2sinx+cosx , x=π/2

sin(π/2)=1, cos(π/2)=0

y(π/2)=2 × 1 + 0 = 2

Answer 2

To find the value of the function y = 2sin(x) + cos(x) when x = π/2, we simply substitute π/2 into the expression for y:

y = 2sin(π/2) + cos(π/2)

Now, we know that sin(π/2) = 1 and cos(π/2) = 0, so we can substitute these values:

y = 2 * 1 + 0

y = 2

Therefore, the value of the function when x = π/2 is y = 2.
