Step 1:  Note down the given equation and known about the complimentary angles

              EXAMPLE: \frac{\sec 35\degree}{ \cosec 55\degree}


Step 2: Using the trigonometric ratio for complementary angles,

            NOTE: we know that, \cosec A = \sec (90\degree - A)  [ \because of complimentary angles ]

            EXAMPLE:  = \cosec 55\degree = \sec (90\degree - 35\degree)

                                = \cosec 55\degree = sec 35\degree.............(1)


Step 3: Insert the known values and solve for the unknown value.

              EXAMPLE: = \frac{\sec 35\degree}{ \cosec 55\degree}

                                              =   \frac{\sec 35\degree}{ sec 35\degree} [since equation (1)]

                                                             =  1
