Download Solution PDFसंकल्पना:
पहली-कोटि वाले अवकल समीकरण के लिए चर को अलग कीजिए और उसीप्रकार समाकलन कीजिए।
समाकलन स्थिरांक ज्ञात करने के लिए दी गयी स्थिति को रखिए।
गणना:
दिया गया अवकल समीकरण
\(\rm \frac{\mathrm{d} y}{\mathrm{d x}} -4y = 0\)
⇒ \(\rm \frac{\mathrm{d} y}{y} =4dx\)
दोनों पक्षों का समाकलन करने पर
⇒ \(\rm \int\frac{\mathrm{d} y}{y} =\int4dx\)
⇒ ln y = 4x + c
⇒ y = e4x + c
अब y(0) = 1
⇒ 1 = e0 + c
⇒ c = 0
∴ y = e4x
