[sin(x) - cos(x)]^2 = sin^2(x) - 2sin(x)cos(x) + cos^2(x) so [sin(x) + cos(x)]^2 + [sin(x) - cos(x)]^2 = sin^2(x) + 2sin(x)cos(x) + cos^2(x) + sin^2(x) - 2sin(x)cos(x) + cos^2(x) [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}\\ & Prove and determine that the trig function (sinx + cosx)^2 + (sinx - cosx)^2 is equal to 2More at http://msolved.com *Response times vary by subject and question complexity.

Sinx cosx 2

1. (sinx osx) sinxcosx. + c. 2. 18 янв 2017 Sin x + cos x = √2*(sin x*1/√2 + cos x*1/√2) = √2*(sin x*cos π/4 + cos x*sin π/ 4) == √2*sin(x + π/4) = √2/2sin(x + π/4) = 1/2x1 + π/4 = π/6 + Hi everyone, First of all, this isn't really a "homework", I've completed my calculus course and I'm just curious about this problem.

What is the measurement of the angle between the two forces?
