tangent of f(x)=14xsin(x),\at x= pi/2

tangent of

f (x) = 14 x sin (x), at x = \frac{π}{2}

y = 14 x

Solution steps

Find the tangent point:

(\frac{π}{2}, 7 π)

Find the slope of

f (x) = 14 x sin (x) : \frac{df ( x )}{d x} = 14 (sin (x) + x cos (x))

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = 14

Find the line with slope m=

14

and passing through

(\frac{π}{2}, 7 π) : y = 14 x

y = 14 x

\int \frac{11 x ^{2}}{( 25 + x ^{2} ) ^{2}} d x

\frac{d}{d x} (\frac{1}{x} - 1)

\int \frac{1}{( 1 + u ^{2} )} d u

\int 30 (x + 2) (x + 3)^{4} d x

f (x) = x^{4} - 3 x^{3} - 9 x^{2} + 5 x
