1. sin (π/6) csc (π/6)
= sin (π/6) * 1/sin (π/6) = 1
2. sec(π/3)cos(π/3) + tan(π/3)cot(π/3)
I think for both questions, they want you to realize that if you multiply a trig function by its reciprocal function you get 1
= 1 + 1 = 2
= sin (π/6) * 1/sin (π/6) = 1
2. sec(π/3)cos(π/3) + tan(π/3)cot(π/3)
