Solve the equation 2cosA = 3tanA
zavuch27 [327]
\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)&#10;\\\\\\&#10;tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}\\\\&#10;-----------------------------\\\\&#10;&#10;2cos(A)=3tan(A)\implies 2cos(A)=3\cfrac{sin(A)}{cos(A)}&#10;\\\\\\&#10;2cos^2(A)=3sin(A)\implies 2[1-sin^2(A)]=3sin(A)&#10;\\\\\\&#10;2-2sin^2(A)=3sin(A)\implies 2sin^2(A)+3sin(A)-2

\bf \\\\\\&#10;0=[2sin(A)-1][sin(A)+2]\implies &#10;\begin{cases}&#10;0=2sin(A)-1\\&#10;1=2sin(A)\\&#10;\frac{1}{2}=sin(A)\\\\&#10;sin^{-1}\left( \frac{1}{2} \right)=\measuredangle A\\\\&#10;\frac{\pi }{6},\frac{5\pi }{6}\\&#10;----------\\&#10;0=sin(A)+2\\&#10;-2=sin(A)&#10;\end{cases}

now, as far as the second case....well, sine of anything is within the range of -1 or 1, so -1 < sin(A) < 1

now, we have -2 = sin(A), which simply is out of range for a valid sine, so there's no angle with such sine

so, only the first case are the valid angles for A
