 = sin30 + tan45 - cosec60 \times sec30 + cos60  + cot45

 =  \frac{1}{2}  + 1 -  \frac{2}{ \sqrt{3} }  \times  \frac{2}{ \sqrt{3} }  +  \frac{1}{2}  + 1

  = \frac{3}{2}  -  \frac{4}{3}  +  \frac{3}{2}

 =  \frac{3}{2}  +  \frac{3}{2}  -  \frac{4}{3}

  = \frac{3  \times 4 + 3 \times 4 - 4 \times 3}{12}

  = \frac{12 + 12 - 12}{12}

  = \frac{12}{12}

 = 1
