" 25.Solve the differential equation: "sec^(2)x" tan "ydx+sec^(2)y tan xdy=0

Solve the differential equation : sec^(2)x tan y dx + sec^(2) y tan x dy = 0

sec^(2)x tan y dx + sec^(2) y tan x dy = 0

Solve the equation: sec^(2)x tan ydx+sec^(2)y tan xdy=0

Find the general solution of the differential equations sec^(2)x tan ydx+sec^(2)y tan xdy=0

Solve the differential equation : sec^2 x tan y dx -sec^2 y tan x dy = 0 given that y = pi/3 at x = pi/4 .
