Question

prove costheta . cosectheta = cottheta​

Answer 1

Step-by-step explanation:

cos0 . cosec0

can be written as cos0/sin0

and we know that cos0/sin0=cot0

LHS=RHS hence proved

(I HAVE TAKEN theta as 0 as a symbol )

Answer 2

Answer:

so your proof is here

Step-by-step explanation:

here given equation-

cos theta . cosec theta = cot theta

taking LHS

cos theta .1/sin theta

cos theta / sin theta

= cot theta

= RHS

(Hence Proved)
