Graphing two polar equation in same graph by mathematica graphics property

Graphing two polar equation in same graph by mathematica graphics property
Question: 2. Load the package Graphics`Graphics` if you have not already done so in this session of Mathematica. DO NOT load it more than once per session. Graph the polar expression on the same axes. Make the graph of the second equation blue and twice as thick as the red graph of the first equation r=Cos[x]Sin[x/Sqrt[2]] .  and r = -0.25 Cos[x].

How to crack and register mathematica by wolfram research

How to crack and register mathematica by wolfram research
Mathematica is a computational software program used in many scientific, engineering, mathematical and computing fields, based on symbolic mathematics. For the students of mid-level or lower-level of economy it is too hard to buy this software. So for them they need to crack it for getting licence and serial key to use.

Finding root by Newton-Raphson Iteration method in Mathematica

 Finding root by Newton-Raphson Iteration method in Mathematica
Newton-Raphson Iteration method of finding root. We will find root by this method in mathematica here. For this method we need to choose any point near root and then try to find out the absolute root according to this method.

By this method if we choose a root
x0 = x0
then the closer root will be
x1 = x0 - f(x0) / f '(x0) and so on...
