Question

If cosec2 0 (1 + cos 0) (1 - cos 0) = k, then find the value of k.
​

Answer 1

Answer:

0 is the answer since 1- cos0 = 0 and total product is 0

Answer 2

Answer:

1

Step-by-step explanation:

(1+ cos theta )(1-cos theta ) = 1 - cos^2 theta

cosec^2 theta ( 1^2 - cos^2 theta)

cosec^2 theta x sin^2 theta

(1/sin^2 theta) X sin^2 theta = 1
