It's been a while I have had calculus, currently revising some numerical analysis.
I am asked to find, using Calculus, intervals containing solutions to the following equation:
$$ 2x\cos(2x) - (x+1)^2 = 0 $$
This exercises are in the context of Calculus Review which covered:
-Limits and Continuity
-Differentiability (Mean Value Theorem, Rolle's Theorem, Extreme Value Theorem)
-Integration
-Taylor Series and Polynomials
I am not sure how to systematically tackle this question. Thanks in advance.
