How do you calculate #sin x = 0.29#?
You will need to use a trigonometry calculator.
The sine function is positive in the first and second quadrants, so we can conclude that sin x will lie between
So, there will be two solutions to this problem. One will occur between
Using a Trig calculator:
The other value, due to symmetry, will equal:
The graph below shows how the line
