where sin 2 θ means (sin θ) 2 and cos 2 θ means (cos θ) 2. This can be viewed as a version of the Pythagorean theorem , and follows from the equation x 2 + y 2 = 1 for the unit circle . This equation can be solved for either the sine or the cosine:
∫ sin2(x)dx = ∫ 1 − cos(2x). 2 dx. = 1. 2 2.
[math]\begin{align*} \sin x\cos x &=\left(\frac{e^{ix}-e^{-ix}}{2i}\right)\left(\frac{e^{ix}+e^{-ix}}2\right)\\ &=\frac{(e^{ix}-e^{-ix})(e^{ix}+e^{-ix})}{4i

Practice Makes Perfect. Learning math takes practice, lots of practice. Just like running, it takes practice and Because sin²x + cos²x = 1 and sinx*cosx = sin(2x)/2, we get: (sinx + cosx)² = 1 + sin(2x) [math]\begin{align*} \sin x\cos x &=\left(\frac{e^{ix}-e^{-ix}}{2i}\right)\left(\frac{e^{ix}+e^{-ix}}2\right)\\ &=\frac{(e^{ix}-e^{-ix})(e^{ix}+e^{-ix})}{4i}\\ & cos(2x) = cos 2 (x) – sin 2 (x) = 1 – 2 sin 2 (x) = 2 cos 2 (x) – 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures.
