noor: what is the angle whose sin is 6/7
can you explain how do we use a calculator for that ?
inverse sin (6/7) = your angle
Inverse sine is the same as arc sine
the notation might be
sin
-1(6/7)
or
asin(6/7)
To bring up inverse sin on a calc you usually have to press '2nd' or 'shift' and then press sin
Remember: Whenever you are looking for an
angle you have to use
inverse trigonometry.
