To find the value of cosec 90°, you first need to understand what cosecant means. Cosecant is the reciprocal of the sine function. This means:
Understanding Cosecant
The cosecant of an angle is defined as:
- cosec(θ) = 1/sin(θ)
Finding sin(90°)
Now, let's find sin(90°). The sine of 90 degrees is:
- sin(90°) = 1
Calculating Cosec 90°
Using the definition of cosecant, we can now calculate cosec 90°:
- cosec(90°) = 1/sin(90°) = 1/1 = 1
Final Answer
Therefore, the value of cosec 90° is 1.
