October 11, 2023 - cosine of 1 rads = 0.5403023058681398 cosine of 0.5 rads = 1.0 cosine 3.141592653589793 rads = 23.140692632779267 cosine of 60.0 degrees = 0.5000000000000001 · In math there are concepts of indeterminate form, positive and negative infinity. A number divided by 0.0 gives infinity, positive or negative depending on the positivity or negativity of that number. You can get indeterminate form in different ways. For example, if you try to divide zero by zero or infinity to infinity. In Java there are special constants from class Double such as Double.NaN (not a number, you may say it’s a kind of indeterminate form), Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY.

use Math.toRadians to convert your degrees to radians to pass to Math.cos for example
double blah = Math.cos(Math.toRadians(50));
I think that is what you are asking. There are quite a lot of similar questions here.

You can use Math.toDegrees()/Math.toRadians()
Converts an angle measured in radians to an approximately equivalent angle measured in degrees/radians.
Note that public static double cos(double a) expect the parameter in radians:
a - an angle, in radians.

Inverse trigonometric functions are, as they are named, inverse. Since a trigonometric function is a function of the form angle -> value, then the inverse has inverted domain and codomain, value -> angle.
So
Before you pass the variable that represents the angle, do you need to convert it from angle to radian
This makes no sense, since you would convert a value which is not an angle. What you want to do is to convert the result of the inverse function to degrees to obtain the value in the same unit you are using, eg:
double angleInRadians = Math.acos(1);
double angleInDegree = Math.toDegrees(angleInRadians);
So in the end you have
degrees -> radians -> trigonometric function -> value
value -> inverse trigonometric function -> radians -> degrees

An inverse sin or cosine function's domain is [-1,1]. So, it would be useful to validate the input before passing it to the method. The result of doing the inverse is an angle. Now, for the result you may want to do conversion from radians to degree. But, you don't need any conversion for the inverse function.

August 9, 2023 - 1. In function main(), firstly the angle is entered in degrees and it is converted into radians. 2. The loop for(i=0; i<=n; i++) is used to calculate the ith term of the series. 3. The nested loop for(j=2; j<=2*i; j++) is used to calculate the factorial of 2i. 4. Finally, the ith term is added to the variable cosine.
