For each of the differential equations in question, find the general solution:
(e^x + e^–x)dy – (e^x – e^–x)dx = 0

Integrating both sides,

Let ( = t

Then,

So,

⇒ y = log t

Or,

+ c

For each of the differential equations in question, find the general solution:

sec²x tan y dx + sec²y tan x dy

For each of the differential equations in question, find the general solution:

y log y dx – x dy = 0

For each of the differential equations in question, find the general solution:(ex + e–x)dy – (ex – e–x)dx = 0
