Step 1: Recall the trigonometric ratios of some specific angles.

            

              

Step 2: Substitute the values of the trigonometric ratios in the given equation

              EXAMPLE: \frac{\sin 30\degree + \tan 45\degree - \cosec 60\degree}{\cot 45\degree + \cos 60\degree - \sec 30\degree}

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


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

                                                                                                        =  1
