[" The particular solution of "],[sec^(2)y tan xdy+sec^(2)x tan ydx=0],[" when "x=y=(pi)/(4)," is "]

sec^(2) y tan x dy + sec^(2) x tan y dx = 0 , " when " x =y = pi/4

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

find the general solution of 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

The solution of the differential equation sec^2y tan x dy+sec^2x tan y dx=0 under the condition x=y=pi/4 is

xdy + 2 ydx = 0 , " when " x=2 , y=1
