By using formula cos²α + sin²α = 1 
   as cosα = √2 therefore (√2)² + sin²α = 1 
                                          sinα = 1 
putting the values of sin and cos in the eqn 
  2 x (1)² + (√2)²/1 + √2 = 2 + 2 +√2 = 4√2 Ans.

qais: when u solve this.... (√2)² + sin²α = 1  ....sin²α = (-1) ...which cant be possible
