Understanding Secant, Cosecant, and Cotangent - High School Math
Card 0 of 2
Question
An angle has a cosine of 
. What will its cosecant be?
An angle has a cosine of
Answer
The problem tells us that the cosine of the angle will be 
. Cosine is the adjacent over the hypotenuse. From here we can use the Pythaogrean theorem:
Now we know our opposite, adjacent, and hypotenuse.
The cosecant is 
.
From here we can plug in our given values.
