Chapter 6: Q. 26 (page 570)

Use antidifferentiation and/or separation of variables to solve the given differential equations. Your answers will involve unsolved constants.
$\frac{d y}{d x} = y \sin 鈦� x$

Short Answer

Expert verified

Ans: The solution of the differential equation $\frac{d y}{d x} = y \sin 鈦� x$ is $y = A e^{鈭� \cos 鈦� x}$

Step by step solution

Step 1. Given information.

given,

$\frac{d y}{d x} = y \sin 鈦� x$

Step 2. Consider the differential equation defined by equation (1) given below and solve it by using antidifferentiation and/or separation of the variable method.

$\frac{d y}{d x} = y \sin x . . . . (1)$

Step 3. Solution

Note that the differential equation (1) is of the form of $\frac{d y}{d x} = p (x) q (y)$ in which $p (x) = \sin x$ and $q (y) = y$ . So the differential equation can be solved by applying the variable separable method. Separate the variables and integrate both the sides

role="math" localid="1649178088966" $\begin{aligned} 鈭� \frac{1}{y} d y = 鈭� \sin 鈦� x d x \\ \ln 鈦� | y | = 鈭� \cos 鈦� x + C \\ y = e^{鈭� \cos 鈦� x + C} \\ = A e^{鈭� \cos 鈦� x} \end{aligned}$

Hence a solution to the differential equation $\frac{d y}{d x} = y \sin x$ is $y = A e^{鈭� \cos 鈦� x}$
