Answered by RAXNIGAM

1

Answer:

answer is -1

Step-by-step explanation:

since

cot theta= cos theta/ sin theta

therefore

cot² theta- 1/sin² theta

cos² theta/sin² theta -1/sin² theta

= cos² theta-1/ sin² theta

since sin² theta+cos² theta= 1

= -sin² theta/sin² theta

= -1

Answer:

cot theta= cos theta/ sin theta

therefore

cot² theta-1/sin² theta

cos² theta/sin² theta -1/sin² theta

= cos² theta-1/ sin² theta

since sin² theta+cos² theta= 1

= -sin² theta/sin² theta

= -1
