RobertSmart replied to the thread Sub-perfect Numbers.
The conjecture that all sub-perfect numbers are powers of 2 is indeed false. A counter-example to this conjecture is 12. To show that...

RobertSmart replied to the thread General solution for differentiation.
a) Starting with 3^2y^2dy/dx=2−1, We can simplify it to 9y^2dy/dx=1. Now, we can separate variables: 9y^2dy=dx Integrating both...

HallsofIvy replied to the thread Transcendental Numbers...1.
Do you remember when calculators did not exist? I do! We used tables of logarithms. \log(e^{\pi}}= \pi \log(e)= 3.1416(0.4343)= 1.3644....

RobertSmart replied to the thread Basic Algebra - Factorising.
To factorize ax^2−b^2, we use the difference of squares formula: ax^2−b^2=(x√a−b)(x√a+b). Given that ax^2−b^2=9x2−4, we identify a=9...
