Answer: dydx=2sec2(x)tan(x)
Step-by-step explanation:
Is it radius or circumference?
Answer:
Step-by-step explanation:
Given: 
.
we need to find the correct form for 
if the equation is solve using undetermined coefficients.
A first order differential equation 
is said to be homogeneous if 
for all t.
Consider homogeneous equation 
Let 
be the solution .
We get 
Since 
, 
.
So, we get solution as 
As constant term and 
are already in the R.H.S of equation
, we can take as
