Find sin(30) = 0.5

Do you have difficulty find the sine of degree / sin(degree) ?

I'll show you how ...

see picture below



For example : you want to get sin(30)
Step 1 : You have to convert the number(30) to radian first.
By typing " =radians(30)"
Step 2 : Add formula "sin" in front of previous formula
" =sin(radians(30))"
Note : Don't forget to add bracket () for each formula
Tips : You can change the value of 30 to any cell, like A5
so if you change any value in cell A5,the result will change

then ... how if you want to find the opposite Asin(0.5)=30 ?

see picture below ...




Step 1 : We use "ASIN" formula, type "=ASIN(0.5)"
Step 2 : Add "DEGREES" formula in front of previous formula
"=DEGREES(ASIN(0.5))" .... don't forget the bracket

Done ....!
