Vedclass · Answer

(B) આપેલ છે કે $y = \frac{\alpha x + \beta}{\gamma x + \delta}$.પ્રથમ વિકલન: $y_1 = \frac{\alpha(\gamma x + \delta) - \gamma(\alpha x + \beta)}{(\gamma x + \delta)^2} = \frac{\alpha \delta - \gamma \beta}{(\gamma x + \delta)^2}$.દ્વિતીય વિકલન: $y_2 = \frac{d}{dx} [(\alpha \delta - \gamma \beta)(\gamma x + \delta)^{-2}] = -2(\alpha \delta - \gamma \beta)(\gamma x + \delta)^{-3} \cdot \gamma = \frac{-2 \gamma(\alpha \delta - \gamma \beta)}{(\gamma x + \delta)^3}$.તૃતીય વિકલન: $y_3 = \frac{d}{dx} [-2 \gamma(\alpha \delta - \gamma \beta)(\gamma x + \delta)^{-3}] = (-2 \gamma)(\alpha \delta - \gamma \beta) \cdot (-3)(\gamma x + \delta)^{-4} \cdot \gamma = \frac{6 \gamma^2(\alpha \delta - \gamma \beta)}{(\gamma x + \delta)^4}$.હવે,$2 y_1 y_3 = 2 \cdot \left( \frac{\alpha \delta - \gamma \beta}{(\gamma x + \delta)^2} \right) \cdot \left( \frac{6 \gamma^2(\alpha \delta - \gamma \beta)}{(\gamma x + \delta)^4} \right) = \frac{12 \gamma^2(\alpha \delta - \gamma \beta)^2}{(\gamma x + \delta)^6}$.વળી,$3 y_2^2 = 3 \cdot \left( \frac{-2 \gamma(\alpha \delta - \gamma \beta)}{(\gamma x + \delta)^3} \right)^2 = 3 \cdot \frac{4 \gamma^2(\alpha \delta - \gamma \beta)^2}{(\gamma x + \delta)^6} = \frac{12 \gamma^2(\alpha \delta - \gamma \beta)^2}{(\gamma x + \delta)^6}$.આમ,$2 y_1 y_3 = 3 y_2^2$.

જો $y = \frac{\alpha x + \beta}{\gamma x + \delta}$ હોય,તો $2 y_1 y_3 =$

જો $y=e^{\sqrt{x \sqrt{x} \sqrt{x} \ldots}}, x>1$ હોય,તો $x=\log _e 3$ આગળ $\frac{d^2 y}{d x^2}$ ની કિંમત શોધો.

જો $f(x)=\tan ^{-1}\left[\frac{\log \left(\frac{e}{x^{2}}\right)}{\log \left(e x^{2}\right)}\right]+\tan ^{-1}\left[\frac{3+2 \log x}{1-6 \log x}\right]$ હોય, તો $f^{\prime \prime}(x)$ ની કિંમત કેટલી થાય?

ધારો કે $f(x)=ax^3+bx^2+cx+41$ એવું છે કે $f(1)=40, f'(1)=2$ અને $f''(1)=4$. તો $a^2+b^2+c^2$ ની કિંમત શોધો:

ધારો કે $f$ એ બે વાર વિકલનીય વિધેય છે જેથી $f^{\prime \prime}(x) = -f(x)$,$f^{\prime}(x) = g(x)$ અને $h(x) = [f(x)]^2 + [g(x)]^2$ થાય. જો $h(5) = 1$ હોય,તો $h(10) = \qquad$

જો $y=3 \cos (\log x)+4 \sin (\log x)$ હોય,તો $x^2 y_2+x y_1=$
