simplify using a mathematical table or calculator {sin(-330)-cos(330)/sin(660)}^-1

Answer 1

To calculate this expression, we can use a calculator.

Using a scientific calculator, we can input the expression as follows:

sin(-330) - cos(330) / sin(660)

The answer will depend on the unit your calculator is set to. However, the final step asks for the inverse, so the unit will not matter.

Using a calculator, the simplified result is approximately equal to -1.31696.
