what is sin and how to convert into decimal??​

Answer 1

Depending on your calculator, yes! Most calculators that have the sin, cos, tan functions also come with sin^(-1), cos^(-1) and tan^(-1) functions!

If tan(30)=0.577, then tan^(-1)(0.577)=30 (if you want this result in DEGREES instead of RADIANS, make sure you change the settings on your calculator (it's different for every calculator).
