Solve the differential equation: dy/dx +...

Solve the differential equation: `dy/dx + y cotx = 4x cosec x`, given that y=0 at x = `pi/2`

Text Solution

Verified by Experts

Comparing the given equation with first order differential equation,
`dy/dx+Py = Q(x)`, we get, `P = cotx and Q(x) = 4xcosecx`
So, Integrating factor `(I.F) = e^(intcotxdx)`
`I.F.= e^(ln|sinx|) = sinx`
we know, solution of differential equation,
`y(I.F.) = intQ(I.F.)dx`
`:.`Our solution will be,
