A.solve [tex]\frac{1}{n} \pi = \theta - \frac{1}{2}sin(2 \theta)[/tex] for [tex] \theta[/tex] in terms of "n"(derivation of equation below)b. based on your answer inpart a, if [tex] \theta = arccos(1 - \frac{a}{r} ) = {cos}^{ - 1} (1 - \frac{a}{r} )[/tex] or [tex] a = r-2cos( \theta)[/tex]find "a" as a function ofr & n. (find f(r,n)=a).alternately, if a+b=r, we can write [tex] \theta = arccos( \frac{b}{r} ) = {cos}^{ - 1} (\frac{b}{r} )[/tex] then solve for "a" in terms of r and nshow all work and reasoning.solve analytically if possible

For the first derivative of f(theta)=2cos(theta)+cos^2(theta), i got f'(theta)=-2sin(theta)+2cos(theta)-sin(theta)=0 after simplifying it, the book had (-sin(+cos(theta))=0 how did they get (1+cos( the answers is prob really simple but i am stuck on it if anyone could kindly . @mathematics
