So we need to do these conversions:  1tonne=1000kg so 5 tonnes is 5x1000kg = 5000kg 

There are 1000km in a meter so 50x1000= 50000m/h to get this...

When dealing with complex numbers and trigonometric functions, always turn to DeMoivre's Theorem that states [cos(θ)+isin(θ)]ⁿ = [cos(nθ)+isin(nθ)]. If we set n=2, the we see a combina...

Here we need to make a U sibstitution. So we take (x+3) and make this equal U so we now have the integral of u^1/2   . dx

In order to s...
