if tan theta = 8/6, 0 less than = to theta less than = to pi/2 what is sin (theta)= cos(theta)=cos (theta)=?
if \: \tan(theta) = (8)/(6) \: 0 \leqslant theta \leqslant \frac{\pi}{2 \: then \: what \: is \: \sin(thta =) \\ \cos(theta \: csc \: theta)

\begin{gathered} \tan \theta=(8)/(6) \\ \\ 0\leq\theta\leq(\pi)/(2) \\ \\ \end{gathered}

Use the next identities:


\begin{gathered} \tan \theta=(\sin \theta)/(\cos \theta) \\ \\ \csc \theta=(1)/(\sin \theta) \end{gathered}

Then, you get that:


\begin{gathered} \sin \theta=8 \\ \cos \theta=6 \\ \csc \theta=(1)/(8) \end{gathered}
