sin 2x - cos 2x austinmw147 austinmw147 06/23/2017 Mathematics High School answered = cos(x) - 4sin 2 (x)cos(x) Note that in line 3, a different formula could be used for cos(2x), but looking ahead you can see that this will work best for solving the equation, since sin(x)cos(x) terms will show up on both sides. Trigonometric equation example problem detailing how to solve cos(x) + sin(2x) = 0 in the range 0 to 360 degrees by substituting trig identities. In this exa For any random point (x, y) on the unit circle, the coordinates can be represented by (cos `theta` , sin `theta` ) where `theta` is the degrees of rotation from the positive x-axis (see attached

$1-\cos^2x = 3\cos^2x$ //Using the Pythagorean identities to substitute in for $\sin^2x$ I then add $\cos^2x$ to both sides yielding: $$1 = 4\cos^2x$$ I then divide by $4$ yielding: $$\frac 1 4 = \cos… 2018-02-26 Integral of sin(x)cos^2(x) & Integral of sin^2(x)cos(x) - How to integrate it step by step using the substitution method!
