xy = c
x2 + y2 = c
y − x = c

Solution
The solution of `dy/ dx` = 1 is y − x = c.
Explanation
`dy/ dx` = 1
∴ dy = dx
Integrating on both sides, we get
`int 1 dy = int 1 dx`
∴ y = x + c
∴ y − x = c

sec2 x tan y dx + sec2 y tan x dy = 0
Solution: sec2 x tan y dx + sec2 y tan x dy = 0
∴ `(sec^2x)/tanx "d"x + square` = 0
Integrating, we get
`square + int (sec^2y)/tany "d"y` = log c
Each of these integral is of the type
`int ("f'"(x))/("f"(x)) "d"x` = log |f(x)| + log c
∴ the general solution is
`square + log |tan y|` = log c
∴ log |tan x . tan y| = log c
`square`
This is the general solution.
