cscx = sinx tan x + cos x
Using xsx x = 1/sin x and tan x = sin x/cos x
Multiplying both sides by cos x
cot x =1
Correct option is d .
Answer: d. cotx=1
Step-by-step explanation: cosecx=sinxtanx+cosx
⇒ cosecx= sinx× +cosx
⇒ cosecx= +cosx
⇒ cosecx=
⇒ cosecx= 1/cosx (since sin²x+cos²x=1)
⇒ 1/sinx=1/cosx
⇒ cosx/sinx=1
⇒ cotx=1
