If I could interpret your question right, it is:
tan(11π3)−2sin(4π6)−34cosec2(π4)+4cos2(17π6)tan(11π3)−2sin(4π6)−34cosec2(π4)+4cos2(17π6)
= tan(4π−π3)−2sin(2π3)−34cosec2(π4)+4cos2(3π−π6)tan(4π−π3)−2sin(2π3)−34cosec2(π4)+4cos2(3π−π6)
=−tan(π3)−2sin(π−π3)−34cosec2(π4)+4cos2(π6)−tan(π3)−2sin(π−π3)−34cosec2(π4)+4cos2(π6)
= −3–√−2sin(π3)−34×(2–√)2+4×(3√2)2−3−2sin(π3)−34×(2)2+4×(32)2
= −3–√−2×3√2−34×2+4×34−3−2×32−34×2+4×34
=−3–√−3–√−32+3−3−3−32+3
= −23–√+32−23+32
= 3−43√23−432
I hope it helps!
