Using the sum difference formula I got the following
[tex] \sin(30 degrees +45 degrees)=sin 30 cos45+cos 30 sin 45 [/tex]
I used the special triangles and got
[tex] (\frac {1}{2})(\frac {1}{\sqrt2})+(\frac {\sqrt3}{2}) (\frac {1}{\sqrt2}) [/tex]
I rationalized the denominator and got
[tex] \frac {\sqrt2+\sqrt6} {4} [/tex]
Did i make any errors? Can someone please verify.
