Question

यदि y = `|(f(x), g(x), h(x)),(l, m, n),(a, b, c)|` है तो सिद्ध कीजिए कि `dy/dx = |(f'(x), g'(x), h'(x)),(l, m, n),(a, b, c)|`।

Solution

y = `|(f(x), g(x), h(x)),(l, m, n),(a, b, c)|`

`dy/dx= |(d/dx (f(x)), d/dx (g(x)), d/dx (h(x))), (l, m, n), (a, b, c)| + |(f(x), g(x), h(x)),(0, 0, 0),(a, b, c)| + |(f(x), g(x), h(x)),(l, m, n),(0, 0, 0)|`

`= |(f'(x), g'(x), h'(x)),(l, m, n),(a, b, c)|`
