Hi

4cos 60 degrees + 3 tanpi/6 = 4%2A%281%2F2%29+%2B+3%281%2F2%29%2F%28sqrt%283%29%2F2%29+=+2+%2B+3%2Fsqrt%283%29

Simplifying by removing the radical in the denominator:

that is: Multiplying both numerator and denominator by sqrt%283%29

 

Perhaps this (cosx,sinx) Summary would be of help to You, in Your studies
