Isolate the angle 2x, by following the reverse "order of operations". Explanation: Step 1: Add 1 to both sides: \displaystyle {2} { {\cos}^ { {2}} {\left ( {2} {x}\right)}}= {1} Step 2: Divide both sides $$\sin 2x + \cos 2x =-1$$ How would I go about solving this equation? Some hint on how to start, so I can try to figure it out on my own.

I found cofunction identities where sin(90° - θ) = cosθ but I'm not sure if that's the same thing. Homework Equations The Attempt at a Solution Cos 2x is also called a Double angle formula as they have 2 or double angles in the trigonometric functions. Practice Cos 2x formula examples and other trigonometric formulas at BYJU'S. We can’t just integrate cos^2(x) as it is, so we want to change it into another form, which we can easily do using trig identities.

Sin 2x Cos 2x is one such trigonometric identity that is important to solve a variety of trigonometry questions. (image will be uploaded soon) Sine (sin): Sine function of an angle (theta) is the ratio of the opposite side to the hypotenuse. In other words, sinθ is the opposite side divided by the hypotenuse. Sin 2x Cos 2x Sin 2x Cos 2x Sin 2x cos 2x is one of the trigonometric identities which is essential for solving a variety of trigonometry related questions.
