Could someone take a look at my work.. im lost.
my work..Code:Find the equation of the tangent line to the curve y= 4 tan x at the point ( pi/4 , 4). The equation of this tangent line can be written in the form y = mx+b
Where did I go wrong? How do I get the equation from the point and the tangent line?Code:using y-y1 = m(x-x1) y - 4tan(x) = 4tan(x- (pi/4)) y - 4tan(x) = 4tan(x) - (pi tan (x)) y = 8tan(x) - pi tan(x) m = 8tan(x) b = pi tan (x)
So using the point-slope equation, we have
Does this make sense?
