Math Problem Statement

Simplify to a single trig function with no denominator.

cosecant, theta, dot, cosine, theta

cscθ⋅cosθ

Solution

The expression csc(θ)cos(θ)\csc(\theta) \cdot \cos(\theta) can be simplified as follows:

Recall that:

csc(θ)=1sin(θ)\csc(\theta) = \frac{1}{\sin(\theta)}

Substitute this into the expression:

1sin(θ)cos(θ)\frac{1}{\sin(\theta)} \cdot \cos(\theta)

This simplifies to:

cos(θ)sin(θ)\frac{\cos(\theta)}{\sin(\theta)}

Now, recall that cos(θ)sin(θ)\frac{\cos(\theta)}{\sin(\theta)} is equal to cot(θ)\cot(\theta) (cotangent of θ\theta).

So, the simplified expression is:

cot(θ)\boxed{\cot(\theta)}
