Question

If

y = e^{x} f i n d \frac{d y}{d x}

Options:

A . ex

B . ex

C . xex−1

D . none of these

Answer: Option A
:
A

\frac{d e^{x}}{d x} = e^{x}

\frac{d y}{d x}

for some common functions

\begin{matrix} y & \frac{d y}{d x} & y & \frac{d y}{d x} x^{n} & n x^{n - 1} & s e c x & s e c x t a n x s i n x & c o s x & c o s e c x & - c o s e c x c o t x c o s x & - s i n x & l n x & \frac{1}{x} t a n x & s e c^{2} x & e^{x} & e^{x} c o t x & - c o s e c^{2} x \end{matrix}
