- Write a method that accepts the length and width of a rectangle and returns the perimeter of the rectangle
- Write a method that accepts the base and height of a triangle and returns the area of the triangle
- Write a method that accepts three integers as paramaters and returns the average of the integers.
- Write a method that accepts an integer array as a parameter and returns the average of the values of that array.
- Write a method that accepts an integer array as a parameter and returns the minium value in that array
- Write a method that returns the hypotenuse of a triangle when the other two sides are int a and int b. (Remember: hypotenuse squared equals a squared plus b squared)
- The scalar product of u=(u1,u2,u3) and v=(v1,v2,v3) is defined to be u1v1+u2v2+u3v3. Write a method that accepts two int arrays as parameters and returns an int representing the scalar product of those two arrays
- If A = (a1,a2, …an) and B = (b1,b2, …bn) then the vector sum of the two arrays A + B = (a1+b1, a2+b2, … , an+bn). Write a method that accepts two arrays as parameters and returns an array representing the vector sum of those two arrays.
- The Euclidean distance between two points A = (a1,a2, …an) and B = (b1,b2, …bn) is defined as sqrt((a1-b1)
^{2}+ (a2-b2)^{2}+… + (an-bn)^{2}). Write a method that accepts two int arrays representing A and B as parameters and returns a double representing the Euclidean distance between them.
