\frac{d}{d x} (e^{x} cos (y))

e^{x} cos (y) - e^{x} sin (y) \frac{d y}{d x}

Solution steps

\frac{d}{d x} (e^{x} cos (y))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = e^{x}, g = cos (y)

= \frac{d}{d x} (e^{x}) cos (y) + \frac{d}{d x} (cos (y)) e^{x}

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

\frac{d}{d x} (cos (y)) = - sin (y) \frac{d y}{d x}

= e^{x} cos (y) + (- sin (y) \frac{d y}{d x}) e^{x}

Simplify

= e^{x} cos (y) - e^{x} sin (y) \frac{d y}{d x}

\int cos^{2} (x) + 2 cos (x) + 1 d x

\int (x^{\frac{3}{4}}) d x

\int \frac{x ^{2} + 1}{x ^{3} + x ^{2}} d x

y e^{x}

\int \frac{1}{9 + ( x - 1 ) ^{2}} d x
