What's the answer to 4sin(theta)=3cos(theta), and how do you get there? Thanks!
There are two solutions on [0, 2pi]
One occurs at about (36.9, 2.4) and the other at about (216.9, -2.4)
These solutions repeat on every 2pi interval
Here's the graph......https://www.desmos.com/calculator/xvemw185zj
4sin(theta)=3cos(theta)
$$\\4sin(\theta)=3cos(\theta)\\\\
\frac{sin\theta}{cos\theta}=\frac{3}{4}\\\\
tan\theta=0.75\\\\
\theta=atan(0.75)$$
$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\mathtt{0.75}}\right)} = {\mathtt{36.869\: \!897\: \!645\: \!844^{\circ}}}$$
