Evaluate the expression \(2 cos(x) + 3 sin(y)\) given that \(cos(x) = \frac{1}{2}\) and \(sin(y) = \frac{3}{5}\).

Step 1 ：Substitute \(cos(x) = \frac{1}{2}\) and \(sin(y) = \frac{3}{5}\) into the expression

Step 2 ：\(2 cos(x) + 3 sin(y) = 2(\frac{1}{2}) + 3(\frac{3}{5})\)

Step 3 ：Simplify the expression to get \(1 + \frac{9}{5}\)

Step 4 ：Convert the fraction to a decimal to get \(1 + 1.8\)
