if x y pi then the value of dfrac dy dx is
Question:
If \(x-y=\pi\), then the value of \(\dfrac{dy}{dx}\) is:
Show Hint
Differentiate x - y = constant directly; the derivative of a constant is 0.

\(\pi\)
1
\(x\)
Show Solution
Verified By Collegedunia
The Correct Option is
C
Solution and Explanation
Step 1: Differentiate both sides w.r.t. \(x\):
\(x-y=\pi\) is an equation between \(x\) and \(y\) with \(\pi\) a constant. Differentiating: \(1-\dfrac{dy}{dx}=0\).
Step 2: Solve for \(dy/dx\):
\[ \dfrac{dy}{dx}=1 \]
Final Answer:
\[ \boxed{\dfrac{dy}{dx}=1} \]
