Cos X Sin X 0

Cos X Sin X 0. There are two ways to solve the equation Your method 2\sin x\cos x+\cos x=0 so \cos x(2\sin x+1)=0 Thus we have either \cos x=0 or \sin x=1/2 .

If any individual factor on the left side of the equation is equal to 0 0 the entire expression will be equal to 0 0 −sin(x)− 1 = 0 sin ( x) 1 = 0 2sin(x)− 1 = 0 2 sin ( x) 1 = 0 Set the first factor equal to 0 0 and solve Tap for more steps Set the first factor equal to 0 0 − sin ( x) − 1 = 0 sin ( x) .

Answer (1 of 5) Answer √2 1 The Calculus Let I = ∫(sin x cos x) dx (Limits of integration are from π/4 to 0) According to a theorem/rule on integration integration of the difference of two functions equals the difference of the integration of the two functions taken separately ∴ I =.

Simplify : tan^1((cosx sinx)/(cosx + sinx)), 0 < x < π

Ta có $\cos x + \sin x = 0 $ $\Leftrightarrow \cos x = \sin x$ \( \Leftrightarrow \cos x = \cos \left( {x + \dfrac{\pi }{2}} \right)\) \( \Leftrightarrow \left[ \begin{array}{l}x = x + \dfrac{\pi }{2} + k2\pi \left( {VN} \right)\\x = x \dfrac{\pi }{2} + k2\pi \end{array} \right\) \( \Leftrightarrow 2x = \dfrac{\pi }{2} + k2\pi \).
