We will use trigonometric identities to solve. We will start from the left side and prove the right side. ==> we know that: 2011-02-26 · So tan(2x) / [sin(2x) + cos(2x)] can become as big as one likes and is as a result unbounded. By the way, a simpler way to see this isn't an identity is to alternative x = pi.

Final Exam and solution

cos 2x = 1 − 2 sin 2 x. Multiply them to get, sin 2x cos 2x = 2 sin x cos x (1 − 2 Sin 2 x) = 2 cos x (sin x – 2 sin 3 x) Explanation: The function is \displaystyle{f{{\left({x}\right)}}}=\frac{{\sin{{x}}}}{{\cos{{x}}}}={\tan{{x}}} .
