Simplify csc(30)

Problem

csc(30)

Solution

1. Identify the definition of the cosecant function in terms of the sine function.

csc(θ)=1/sin(θ)

2. Substitute the given angle of 30 into the identity.

csc(30)=1/sin(30)

3. Recall the exact value of sin(30) from the unit circle or a special right triangle.

sin(30)=1/2

4. Simplify the expression by calculating the reciprocal of the sine value.

csc(30)=1/(1/2)

csc(30)=2

Final Answer

csc(30)=2
