Write a Java expression for the following:

5/10+ x5 + 4/ bx3

Ans.

5.0/10.0 + Math.pow(x,5) + 4.0/ b * Math.pow(x, 3)

Write the Java expression for

ax5 + bx3 + c

Ans.

a * Math.pow(x, 5) + b * Math.pow(x, 3) + c

Write down java expression for :

T = square root (A2 + B2 + C2)

Ans.

double T = Math.sqrt(Math.pow(A, 2) + Math.pow(B, 2) + Math.pow(C, 2));

Write the Java expression for:

(A2 + B2 )/ 2ab

Ans.

(Math.pow(a, 2) + Math.pow(b, 2)) / (2 * a * b)

Write the java expressions for each of the following:

(i) x = e|2x – 4x|

(ii) s=√(sin(a) + tan(a) – e2x)

Ans:

(i) x = Math.exp(Math.abs(2*x-4*x))

(ii) s = Math.sqrt(Math.sin(a)+Math.tan(a)-Math.exp(2*x))

Write an expression for:

Ans.

(x + Math.pow (y, 2)) / (Math.cbrt(3)+y)

Write Java expression for following.

Ans.

x= a*b+(1.0/2.0)*c*Math.pow(b,2);

Write an expression in java for:

Ans.

A= ( Math.pow((a+b),2 ) * Math.pow((a-b),3)) / 2*a*b

Write an expression in java for:

Ans.

X=Math.abs(A)+ Math.abs(B) +(Math.pow(A,3)+ Math.pow(B,4))
