2008-11-17 How do we solve this integration? $$\int\cos(2 x) \sqrt{\sin^2(x) + 1}\, dx.$$ I used WolframAlpha, the result is $$\frac{1}{6}\left(8 \,F(x\mid-1) - 6\, E(x\mid-1 [cosx cosy-sinx siny] + i[cosxsiny + sinx cosy] So the formula e ix =cos x + i sin x is consistent (at least this much) with the exponent law we've just tested. If we tried ( e ix ) 2 = e 2 ix or ( e ix ) 3 = e 3 ix and so on, we'd get the same result. 2015-04-06 Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

2. + C är en primitiv funktion till f(x) = sin 2x eftersom. F (x) = −. 2(− sin 2x). 2 x cos x dx = x sin x − ∫ sin x · 1 dx = x sin x + cosx + C. Övertyga dig Cau (x + 3) = ( x x. Frun derra och detnitionerna au sin , cas och ran, Folper att sin (-x) = - sinx cos(-x) = cost.

You should just use the summation formula for sines: \sin (x + y) = \sin (x)\cos (y) + \cos (x)\sin (y) This is how it works \eqalign { \sin (x) + \cos (x) &= \sqrt 2 \left ( { {1 \over {\sqrt 2 }}\cos (x) + {1 \over {\sqrt 2 }}\sin (x)} \right) \cr &= \sqrt 2 \left ( {\sin ( {\pi \over 4})\cos (x) + \cos ( {\pi \over 4})\sin (x)} \right) \cr &=

Solving for sin^2 (x) gives. sin^2 (x)=1-cos^2 (x) Apply this to the instance of sin^2 (x) in the equation: cos (2x)cos (x)+2cos (x) (1-cos^2 (x))=1.
