Many computations can be expressed concisely using the “multadd” operation, which takes three operands and computesa*b + c. Some processors even provide a hardwareimplementation of this operation for floating-point numbers.
a. Create a new program calledMultadd.java.
b. Write a method calledmultaddthat takes threedoublesas parameters and thatprints their multadditionization.
c. Write amainmethod that testsmultaddby invoking it with a few simple parameters, like1.0, 2.0, 3.0, and then prints the result, which should be5.0.
d. Also inmain, usemultaddto compute the following values:
sin(π4)+cos(π4)2 {"version":"1.0","size":{"width":"161","height":"74","auto":true},"math":""}" role="presentation" style="display: inline; line-height: normal; font-size: 13.3333px; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">sin(π4)+cos(π4)2{"version":"1.0","size":{"width":"161","height":"74","auto":true},"math":"sin(π4)+cos(π4)2"}
log 10 + log 20
e. Write a method calledyikesthat takes a double as a parameter and that usesmultaddto calculate and print
xe−x+1−e−x {"version":"1.0","size":{"width":"161","height":"50","auto":true},"math":""}" role="presentation" style="display: inline; line-height: normal; font-size: 13.3333px; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">xe−x+1−e−x−−−−−−√{"version":"1.0","size":{"width":"161","height":"50","auto":true},"math":"xe−x+1−e−x"}
HINT: the Math method for raisingeto a power isMath.exp.
In the last part, you get a chance to write a method that invokes a method you wrote. Whenever you do that, it is a good idea to test the first method carefully before you start working on the second. Otherwise, you might find yourself debugging two methods at the same time, which can be very difficult. One of the purposes of this exercise is to practice pattern-matching: the ability to recognize a specific problem as an instance of a general category of problems.
