Example Question #3 : Trigonometry
An angle has a cosine of . What will its cosecant be?
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.
Example Question #4 : Trigonometry
Which of these is equal to for angle ?
, as it is the inverse of the function. This is therefore the answer.
