tangent of f(x)= 7/x ,\at x=2\lor ,x=7

tangent of

f (x) = \frac{7}{x}, at x = 2 or, x = 7

y = - \frac{7}{4} x + 7

Solution steps

Find the tangent point:

(2 or, \frac{7}{2})

Find the slope of

f (x) = \frac{7}{x} : \frac{df ( x )}{d x} = - \frac{7}{x ^{2}}

Compute the slope of

f (x) = \frac{7}{x}

x = 2 or : m = - \frac{7}{4}

Find the line with slope m=

- \frac{7}{4}

and passing through

(2 or, \frac{7}{2}) : y = - \frac{7}{4} x + 7

y = - \frac{7}{4} x + 7

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

\frac{d}{d x} (x^{2} + 4 y, 3 x)

\int_{0}^{\frac{π}{2}} cos^{3} (15 x) d x

\frac{d}{d x} (11 arctan (x))

\int \frac{1}{tan ( u )} d u
