(cos²Ф - 1) / sin Ф * 1/sin Ф=
1(cos²Ф-1) / (sin Ф* sinФ)=
(cos²Ф-1) / sin² Ф=
--------------------------------------------------------------
Fundamental relation of trigonometry:
sin²Ф + cos²Ф=1 ⇒ sin²Ф=1-cos²Ф ⇒
-sin²Ф=cos²Ф-1
--------------------------------------------------------------
-sin²Ф/sin²Ф=1
