All trig ratios have an "arc" function or in other words an inverse function

'; explain[1] = '#2

Equations that have trig ratios in them, can be solved by using the inverse trig functions.

'; explain[2] = '#3

All six trig ratios have an inverse function

'; explain[3] = '#4

The law of sines is a very useful tool for finding values on a non right triangle. The Law of sines also involves fractions

'; explain[4] = '#5

The law of cosines is a very useful tool for finding values on a non right triangle.
