જો $x=f(t)$ અને $y=g(t)$ એ $t$ ના વિકલનીય વિધેયો હોય,તો $\frac{d^2 y}{d x^2}$ શું થાય?

  • A
    $\frac{f^{\prime}(t) \cdot g^{\prime \prime}(t)-g^{\prime}(t) \cdot f^{\prime \prime}(t)}{\left[f^{\prime}(t)\right]^3}$
  • B
    $\frac{f^{\prime}(t) \cdot g^{\prime \prime}(t)-g^{\prime}(t) \cdot f^{\prime \prime}(t)}{\left[f^{\prime}(t)\right]^2}$
  • C
    $\frac{g^{\prime}(t) \cdot f^{\prime \prime}(t)-f^{\prime}(t) \cdot g^{\prime \prime}(t)}{\left[f^{\prime}(t)\right]^3}$
  • D
    $\frac{g^{\prime}(t) \cdot f^{\prime \prime}(t)+f^{\prime}(t) \cdot g^{\prime \prime}(t)}{\left[f^{\prime}(t)\right]^3}$
