What is the degree of d²y/dx² = √(1+dy/dx)?

C. degree not defined

Step 1: Identify the concept: degree of DE. Step 2: A derivative is inside a radical, so the equation is not polynomial in derivatives and degree is not defined. Step 3: Exam tip: Degree is defined only when derivatives are in polynomial form.

Step 1: अवधारणा degree of DE है। Step 2: Derivative radical के अंदर है, इसलिए equation polynomial in derivatives नहीं है और degree defined नहीं है। Step 3: याद रखें: Degree तभी defined है जब derivatives polynomial form में हों।
