tangent of f(x)=5tan(x),\at x=1.57

tangent of

f (x) = 5 tan (x), at x = 1.57

y = 7884741.10398 \dots x - 12372764.70530 \dots

Solution steps

Find the tangent point:

(1.57, 5 tan (1.57))

Find the slope of

f (x) = 5 tan (x) : \frac{df ( x )}{d x} = 5 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 = 7884741.10398 \dots

Find the line with slope m=

7884741.10398 \dots

and passing through

(1.57, 5 tan (1.57)) : y = 7884741.10398 \dots x - 12372764.70530 \dots

y = 7884741.10398 \dots x - 12372764.70530 \dots
