Rajasthan Board RBSE Class 12 Maths Chapter 12 Differential Equation Ex 12.1

Find the order and degree of the following differential equations :

Question 1.
dyd/x = sin 2x + cos 2x
Solution:
dy/dx = sin 2x + cos 2x
The highest derivative of y = dy/dx = (d¹y/dx¹)1
Thus, order = 1, degree = 1.

Question 2.
d²y/dx² = sin x + cos x
Solution:
d²y/dx² = sin x + cos x
The highest derivative of y = d²y/dx² = (d²y/dx²)1
Thus, order = 2, degree = 1.

Question 3.

Solution:

The highest derivative of y =

Thus, order = 2, degree = 2.

Question 4.

Solution:

Question 5.

Solution:

Question 6.
xdx + ydy = 0
Solution:
x dx + y dy = 0

Thus, order = 1, degree = 1.

Question 7.

Solution:

Question 8.

Solution:

Thus, order = 1 degree = 2.
