Magnitude:Find the square root of 3^2+5^2=root of 34=5.83N (3sf)Direction:Draw a triangle with 3N at the bottom, 5N going up and the hypotenuse then represents the resultant force.The di...
First let's consider the case of even numbers. Suppose n is even, then it must be double some other number, so we have:n = 2kWhere k is another natural number. We want to find out what:1...
The first step is to recognise that, by the chain rule, dy/dx = dy/dt * dt/dx. dy/dt and dt/dx can both be found by differentiating the functions given in the question, to give dy/dt and dx/dt. dt/d...
The 3 terms of this equation can be integrated separately. The general integration of xn is (xn+1)/n+1 where n is a real number not equal to -1. This can be applied to the terms 2xAnswered by Adrien F. • Maths tutor3184 Views
The exponential function is defined as a power series, which we may (for reasons that are beyond the scope of A-level) differentiate term by term to get another power series. The general term of the serie...
