    Question :-

    Evaluate :-  \sin² \:  30°  \cos² \:  45°+ 4  \tan²  \: 3 0° + 1/2  \sin²  \: 60°

    Answer :-

     \sin² \:  30°  \cos² \:  45°+ 4  \tan²  \: 3 0° + 1/2  \sin²  \: 60°

     =  (\frac{1}{4}  \times   \frac{1}{2} )  + (4 \times  \frac{1}{3}) +  (\frac{1}{2}   \times  \frac{3}{4} )

     =  \frac{1}{8}  +  \frac{4}{3} +  \frac{3}{8}

     =  \frac{3 + 32 + 9}{24}

     =  \frac{44}{24}

     =  \frac{11}{6}
