Verify trig identity. show steps and give reason for each step. (cosx)(tanx)(cscx)=1

Tan(x) = sin(x) / cos(x)
Csc(x) = 1/ sin(x)

You'll see this better if I use latex.



Now just cancel numerators with denominations. They all disappear. The cancelations leave 1 on both the numerator and denominator.

Cosine = adjacent / hypotenuse
tangent = opposite / adjacent
cosecant = hypotenuse / opposite
So if we multiply these 3 we get a numerator of
adjacent * opposite * hypotenuseand a denominator ofhypotenuse * adjacent * opposite

We have a numerator and a denominator that equal each other giving us a value of 1.

The mathematical term that cannot be precisely defined is the point. A point has a location but no specific size. It can describe a location but you can never determine its actual size. Imagine the point at the end of the previous sentence. And then imagine it getting smaller and smaller until it disappears. We can only use a dot to represent the point.
