If cos θ + sec θ = 2, then the value of cos^6 θ + sec^6 θ is

In this video, we covered two questions

[1] If cos θ + sec θ = 1/2, then the value of cos3 θ +  sec3 θ is       

      (A) -1     (B) 0     (C) 1     (D)  -11/8   

If A + B = 45°, then the value of (cot A -1) (cot B -1)

If A + B = 45°, then the value of (cot A -1) (cot B -1)

    (a) -1

    (b) 0

    (c) 1

    (d) 2
