Question

If sin 0 = x and sin 0 = y , then tan 0 is a) xy b) x/y c) y/ x d) 1 / xy​

Answer 1

Step-by-step explanation:

Correct option is

−

x

y

cosxy(xy

′

+y)−sinxy(xy

′

+y)=0

(xy

′

+y)(cosxy−sinxy)=0

So,y

′

=

x

−y

(Since, sinxy



=cosxy )

Answer 2

Step-by-step explanation:

if the other one is cos x =0 then

tan 0

=sin 0

cos 0

= x/y

so b is correct option
