Question

, if cosec theta is equals to under root 5 then find the value of 2 - sin squared theta minus cos squared theta

Answer 1

Answer:

7/5

Step-by-step explanation:

cosec theta=root 5

draw a triangle

in which hypote. is root 5 and base is 1 then by applying pythagor. theorem perpendiculr=2

then

sin theta=2/root5

cos theata=1/root 5

and sq them and then put in the given eq.

ans will be 7/5
