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

Question

Accepted Answer

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