What is the slope of the line normal to the tangent line of #f(x) = cosx-cos^2x +1 # at # x= (17pi)/12 #?
Slope of the normal to the tangent line
From the given equation
Obtain the first derivative
Using trigonometric formulas like half-angle formulas and sum/difference formulas
Now, we have to solve for the slope of the normal line
God bless.....I hope the explanation is useful.
