Question

Find coseco - 1 by cosec theta ​

Answer 1

Answer:

solution of    ( cosec Ф - 1 ) / (cosec Ф)     is  (1 - sin Ф)

Step-by-step explanation:

we are to find the value of

( cosec Ф - 1 ) / (cosec Ф)

⇒ (cosec Ф/cosec Ф) - (1/cosec Ф)

⇒1 - (1/cosec Ф)

we know that  sin Ф = (1/cosec Ф)

substitute (1/cosec Ф) value in     [1 - (1/cosec Ф)]

⇒ 1 - sin Ф

solution of    ( cosec Ф - 1 ) / (cosec Ф)     is  (1 - sin Ф)
