Thread: Converting from formulas to java code Math.pow

Hi guy,

I am new to Java and working on converting these two formulas to Math.pow. I do not think what I did is right. I would really appreciate your comment.

1- z equal ((x^(2)*5y)^(24))/(\sqrt(y))

I tried Mat.pow (x,2) * (5*y) *24 / Math.pow (y * 0.5)

2- z equal ((x^(2)*5y)^(24))/(xy)

I tried ((Math.pow (x,2) * 5 * y), 24 ) /(x*y)

In both cases there are two '^' operators in the numerator (top) of the fraction, so I would expect two uses of Math.pow in each numerator. But you only have one.

Break the expressions up into small pieces and translate one at a time into code. Eg

x squared ... times 5y ... to the power of 24 ... all divided by the square root of y

If you think something is wrong, say what it is: unexpected answer, runtime exception, compiler message, etc.

I see. There is a power twice. x, y. How to write it correctly to come away with the correct answer? How much different answers were there? A lot? Math.pow

I think you might be getting an incorrect ans because of 4/3 in Integer Math give 1 and not 1.33 Try changing you code to what is give below. I tried and worked fine for me.

radius = diameter / 2.0d;
volume = (4.0d / 3.0d) * Math.PI * Math.pow(radius, 3);[COLOR="Silver"]
