Ex 9.4, 16 A homogeneous differential equation of the from šš„/šš¦=ā(š„/š¦) can be solved by substitution. (A) š¦=š£š„ (B) š£=š¦š„ (C) š„=š£š¦ (D) š„=š£ Given šš„/šš¦ = h(š„/š¦) Here, h(š„/š¦) is a function of š„/š¦ So, we will make the substitution x = vy So, the correct answer is (c) Note: An example of function h(š„/š¦) can be h(š„/š¦) = (š^(š„/š¦)ā1)/(š„/š¦) So, we solve it by substituting x = vy
