प्रश्न
Integrate the following with respect to the respective variable : `(3 - 2sinx)/(cos^2x)`
Advertisements
उत्तर
Let I = `int (3- 2sinx)/(cos^2x)*dx`
= `int(3/(cos^2x) - (2sinx)/(cos^2x))*dx`
= `3 int sec^2x*dx - 2int sec x tanx*dx`
= 3 tan x – 2 sec x + c.

Solve the differential equation (x2 + y2) dx - 2xy dy = 0 by completing the following activity.
Solution: (x2 + y2) dx - 2xy dy = 0
∴ `dy/dx=(x^2+y^2)/(2xy)` ...(1)
Puty = vx
∴ `dy/dx=square`
∴ equation (1) becomes
`x(dv)/dx = square`
∴ `square dv = dx/x`
On integrating, we get
`int(2v)/(1-v^2) dv =intdx/x`
∴ `-log|1-v^2|=log|x|+c_1`
∴ `log|x| + log|1-v^2|=logc ...["where" - c_1 = log c]`
∴ x(1 - v2) = c
