Question

Sin2°cos28°+sin28°cos2°

Answer 1

Sin(2+30)=sin30=pi/6

Answer 2

To evaluate the expression sin(2°)cos(28°) + sin(28°)cos(2°), we can use the trigonometric identity:

sin(A + B) = sin(A)cos(B) + cos(A)sin(B)

In this case, we have A = 2° and B = 28°. So, we can rewrite the expression as:

sin(2° + 28°)

Now, let's calculate the value of sin(30°):

sin(30°) = 1/2

Therefore, the expression sin(2°)cos(28°) + sin(28°)cos(2°) is equal to 1/2.
