tangent of f(x)=tan(x),\at x=pi

tangent of

f (x) = tan (x), at x = π

y = x - π

Solution steps

Find the tangent point:

(π, 0)

Find the slope of

f (x) = tan (x) : \frac{df ( x )}{d x} = sec^{2} (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

(π, 0) : y = x - π

y = x - π
