cscϕ/secϕ = (1+cotϕ)/(1+tanϕ)
LHS = (1+cotϕ)/(1+tanϕ)
where cotϕ=cosϕ/sinϕ and tanϕ = sinϕ/cosϕ
= (1+(cosϕ/sinϕ))/(1+(sinϕ/cosϕ))
= ((cosϕ+sinϕ)/sinϕ)/((cosϕ+sinϕ)/cosϕ)
= cosϕ/sinϕ
wkt cosϕ=1/secϕ
and sinϕ=1/cosecϕ
= cscϕ/secϕ
LHS = RHS
hence prooved

sdklvkb:
thanks
what is your real name
bt I need to prove 1+secΦ
my answer is wrong
yh
okk
koi baat
next time try karunga
hmm
aap konsi class me ho
