tangent of f(x)=-4cos(x),\at x= pi/2

tangent of

f (x) = - 4 cos (x), at x = \frac{π}{2}

y = 4 x - 2 π

Solution steps

Find the tangent point:

(\frac{π}{2}, 0)

Find the slope of

f (x) = - 4 cos (x) : \frac{df ( x )}{d x} = 4 sin (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 = 4

Find the line with slope m=

4

and passing through

(\frac{π}{2}, 0) : y = 4 x - 2 π

y = 4 x - 2 π

\int x^{2} e^{2} x d x

\int (x^{2} - 1) e^{x} d x

\frac{\partial}{\partial x} (3 x^{2} + 9 y^{2} - x y + x)

\int \frac{x ^{3} + 5 x ^{4} - 7 x}{x ^{2}} d x

\int_{1}^{2} 5 x - 1 d x
