Solve the equation exactly overbthe interval [0,360)<br><br> Sin^2x-cos^2x=0
trasher [3.6K]
\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)\\\\&#10;-----------------------------\\\\

\bf sin^2(x)-cos^2(x)\implies sin^2(x)-[1-sin^2(x)]=0&#10;\\\\\\&#10;sin^2(x)-1+sin^2(x)=0\implies 2sin^2(x)=1\implies sin^2(x)=\cfrac{1}{2}&#10;\\\\\\&#10;sin(x)=\pm\sqrt{\cfrac{1}{2}}\implies \measuredangle x=sin^{-1}\left( \pm\sqrt{\cfrac{1}{2}} \right)\iff \measuredangle x=sin^{-1}\left( \pm\cfrac{\sqrt{2}}{2} \right)&#10;\\\\\\&#10;\measuredangle x=&#10;\begin{cases}&#10;\frac{\pi }{4}\\\\&#10;\frac{3\pi }{4}\\\\&#10;\frac{5\pi }{4}\\\\&#10;\frac{7\pi }{4}&#10;\end{cases}

(?,5) is on the line 4x-7y=1. Find the other half of the coordinate.
ludmilkaskok [199]
The coordinate is an ordered pair (x,y). We have a number, 5, for y, which we can substitute (plug-in) for y in the equation of the line and solve for x.

4x-7y=1\\4x-7(5)=1\\4x=36\\x=9
