tangent of y=9cos(x),(pi/3 ,4.5)

tangent of

y = 9 cos (x), (\frac{π}{3}, 4.5)

y = - \frac{9 3}{2} x + 12.66209 \dots

Solution steps

Find the slope of

y = 9 cos (x) : \frac{d y}{d x} = - 9 sin (x)

Compute the slope of

y = 9 cos (x)

(\frac{π}{3}, 4.5) : m = - \frac{9 3}{2}

Find the line with slope m=

- \frac{9 3}{2}

and passing through

(\frac{π}{3}, 4.5) : y = - \frac{9 3}{2} x + 12.66209 \dots

y = - \frac{9 3}{2} x + 12.66209 \dots

\frac{d}{d x} (x e^{\frac{1}{2} x})

\int \frac{x ^{6}}{x ^{14} - 3} d x

(0, 3), (1, 5)

x \to 6 lim (7)

\int \frac{sin ( x )}{( 3 + cos ( x ) ) ^{2}} d x
