Question 1002349: Find sin(u/2) given that tan(u)=12.287

You can put this solution on YOUR website! Find sin(u/2) given that tan(u)=12.287
----
By definition, tan = y/x
So, y = 12.287 and x = 1
------
Then r = sqrt[12.287^2 + 1^2] = sqrt[151.97] = 12.327
-----
Therefore: cos(u) = x/r = 1/12.327
-----
Your Problem::
sin(u/2) = sqrt[(1-cos(x))/2]
----
Ans: sin(u/2) = sqrt[0.9189/2] = 06778
