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

tangent of

y = 4 sin (x) cos (x), at x = \frac{π}{4}

y = 2

Solution steps

Find the tangent point:

(\frac{π}{4}, 2)

Find the slope of

y = 4 sin (x) cos (x) : \frac{d y}{d x} = 4 cos (2 x)

Compute the slope of

y = 4 sin (x) cos (x)

x = \frac{π}{4} : m = 0

Find the line with slope m=

0

and passing through

(\frac{π}{4}, 2) : y = 2

y = 2

4 x^{2} + 4 x + x y = 4

n \to \infty lim (1000 (1.06)^{n})

y^{^{''}} + y = 0, y (\frac{π}{3}) = 4, y^{^{'}} (\frac{π}{3}) = - 8

e^{x}, e^{- 4 x}, [0, ln (4)]

f (x) = 5 x^{3} - 5 x, at x = 1
