Question

Sin(cot+cos(tan))=cos+sin^2
an explanation would be helpful

Answer 1

sorry, your supposed to prove it using iddentities

Answer 2

do you type it correct ?

Answer 3

start by writing tan = sin/cos
cot = cos/sin

Answer 4

given that
Sin(cot+cos(tan))=cos+sin^2
then
Sin(cot+cos(tan)) can also writen as Sin(cot+cos(sin/cos))
then Sin(cot+sin)
sin((cos/sin)+sin)= (sin(cos/sin)+sin*sin)= cos+sin^2

Answer 5

yes thankss
