Trigonometric methods

[Rekha Sivadasan]

Which methods does java.lang.Math include for trigonometric computations?
a) sin()
b) cos()
c) tan()
d) aSin()
e) aCos()
f) aTan()
g) toDegree()
The answer for this is only a,b & c. Why aren't the rest considered to be trinometric functions? Trignometry is not my cup of tea. So please explain.

Hi,
If you look in the API those methods are called asin(), acos() and atan() all in lowercase.
I hope they dont ask questions like this in the exam.

[Rekha Sivadasan]

yep you are right Mafalda. They are in lowercase , while the last one is toDegrees() instead of toDegree().
Thanks

I just passed the exam and, yes, tricky things like this ARE on the exam. The exam was very tough, but that should keep its value high.
