Find the equation of the tangent line to the curve
y = 2 x cos x \displaystyle {y}={2}{x}{\cos{{x}}} y = 2 x cos x
at the point
( π , − 2 π ) \displaystyle {\left(\pi,-{2}\pi\right)} ( π , − 2 π ) .
The equation of this tangent line can be written in the form
y = m x + b \displaystyle {y}={m}{x}+{b} y = m x + b where
m = \displaystyle {m}= m = Preview Question 6 Part 1 of 2
and
b = \displaystyle {b}= b = Preview Question 6 Part 2 of 2
