tangent of f(x)=x-5sin(x),\at x= pi/2

tangent of

f (x) = x - 5 sin (x), at x = \frac{π}{2}

y = x - 5

Solution steps

Find the tangent point:

(\frac{π}{2}, \frac{π}{2} - 5)

Find the slope of

f (x) = x - 5 sin (x) : \frac{df ( x )}{d x} = 1 - 5 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 = 1

Find the line with slope m=

1

and passing through

(\frac{π}{2}, \frac{π}{2} - 5) : y = x - 5

y = x - 5
