Question

3cos60*sin30................​

Answer 1

3*1/2*1/2=3/4

cos60=1/2

sin30=1/2

Answer 2

To calculate the value of 3cos(60°)sin(30°), you can use trigonometric identities.

1. First, calculate the value of cos(60°) and sin(30°):

• cos(60°) = 0.5
• sin(30°) = 0.5

2. Now, multiply these values together:

3 * cos(60°) * sin(30°) = 3 * 0.5 * 0.5 = 0.75

So, 3cos(60°)sin(30°) is equal to 0.75.
