Solution The problem of this contest was to solve the exponential integral numerically: I implemented an example solution in java which takes your a number x as input and integrates between 1/x and x by

Solution The problem of this contest was to proof euler's function: This can be done using taylor series at x = 0 because all 3 functions are continuous and have continuous derivatives: You can see the

Here you can solve interesting problems using whatever programming language you like. Also you will earn SBI and sometimes STEM by doing so. Also you might learn new things by doing so. The tasks will

Here you can keep your brain fit by solving math related problems and also earn SBI or sometimes other rewards by doing so. The problems usually contain a mathematical equation that in my opinion is fun

Solution The problem of this contest was to solve the differential equation for the pendulum numerically: I implemented an example solution in java which also plots a graph of the angle of the pendulum

Solution The problem of this contest was to find the logarithm of a complex number: This can be done easily using euler's formula: e^(x+iy) = e^x * (cos(y) + i*sin(y)) = e^x *cos(y) + e^x *i*sin(y) = a+bi

Solution The problem of this contest was to sum up all numbers smaller than 1 000 000 which are not divisible by a number less then 100, but are not prime. The solution is just a simple brute force calculation

Solution The problem of this contest was to solve an infinite sum: There are in general 3 different intuitive ways to find a solution to this: 1-1+1-1+1-1+… = (1-1)+(1-1)+(1-1)+… = 0+0+0+… = 0 1-1+1-1+1-1+…

Here you can solve interesting little problems using whatever programming language you like. Also you will earn SBI and STEM by doing so. The tasks will be rather hard to solve without a programmable computer
