Question

My homework is asking me to Find an equation of the tangent line at the point (pi/6, y(pi/6), what is y(pi/6)?

Answer 1

y = f(x) = ?

Answer 2

where is the rest of the question ?

Answer 3

y=sin(5x)+cos(4x)

Answer 4

think of that function as :

y = f(x) = sin(5x) + cos(4x)

Answer 5

y(pi/6) = f(pi/6) = sin(5pi/6) + cos(4pi/6)

Answer 6

they just mean the value of function evaluated at x=pi/6

Answer 7

Is x equal to sin(5pi/6) + cos(4pi/6) then?

Answer 8

y = sin(5pi/6)+cos(4pi/6) when x=pi/6

Answer 9

It just clicked with me! Thanks for the help!!!
