Each expression simplifies to a constant, a single function, or a power of a function. Use fundamental identities to simplify each expression. csc² t - 1

Hello, today we're going to be simplifying the given trigonometric expression and we'll be writing our answer as a single function. So the expression given to us is cotangent squared of X plus one. How can we go about simplifying this trigonometric expression? Well, there is one Pythagorean identity that we can use. Recall that the Pythagorean identity for cos seeking A squared is equal to cotangent squared of X plus one. Notice that the given expression matches the right hand side of this trigonometric identity. What this means is that we can use this identity to simplify the trigonometric expression as kig and squared of X. This is going to be the simplest form of the given trigonometric expression. And with that being said, the answer to this problem is going to be C so I hope this video helps you in understanding how to approach this problem. And I'll go ahead and see you all in the next video.
