Find the equation of the tangent line to the curve y=2sinx

1 answer:

8 0

Hello
f(x) = 2sin(x)
f(π/6) = 1
f'(x) 2cos(x)
f'(π/6) = 2×co(π/6) = 2 × root(3)×0.5 =root(3)
The equation of this tangent line is : y= root(3)(x-π/6)+1
y = root(3)x+1 - π/6(root(x)) in the form y=mx+b
m = root(3) and b = 1 - π/6(root(x))

11 hours and 15 minutes because doing 2.25, which is equal to 2 hours and 15 minutes, times 5 you end up getting 11.25, and converting that to time you get 11 hours and 15 minutes.
