Question

If y=ė‐⁷x than dy/dx is?​

Answer 1

Step-by-step explanation:

Correct option is

B

x−x2−y2y

y=xtany ⟶(1)

 diff. both sides w.r.t. x

 dxdy=1⋅tany+xsec2y⋅dxdy 

dxdy[1−xsec2y]=tany

 dxdy=1−xsec2ytany ⟶(2)

 from eqn (1)     tany=xy

 tan2y=x2y2

 sec2y−1=x2y2 

 sec2y=1+x2y2

 But value of sec
