tangent of y=sin(2x),\at x=(3pi)/4

tangent of

y = sin (2 x), at x = \frac{3 π}{4}

y = - 1

Solution steps

Find the tangent point:

(\frac{3 π}{4}, - 1)

Find the slope of

y = sin (2 x) : \frac{d y}{d x} = cos (2 x) \cdot 2

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 = 0

Find the line with slope m=

0

and passing through

(\frac{3 π}{4}, - 1) : y = - 1

y = - 1
