In Python, write a recursive function that returns the first n Fibonacci numbers.

Begin by denoting the first and second Fibonacci number as 0 and 1 respectively. This helps us define a base case for our algorithm. We know that new Fibonacci numbers are formed by adding its 2 predecessors...

If h(x) = 2xsin(2x), find h'(x).

Differentiate using product rule as expression consist of two functions.Product Rule: d(f(x)g(x))/dx = g(x).f'(x) + f(x).g'(x)Chain Rule: d(f(g(x)))/dx = g'(x) . f'(g(x)) Let: f(x) = 2x f'(x) = 2 - simple di...

A straight line runs through these two coordinates (1,5) and (4,7), find the equation of the line.

Given that the equation is a straight line we know that it will take the form of y = mx + c with m as the gradient and c as the y-intercept. We can find the slope by doing (y 1 - y 2 )/(x 1 -x 2 ) = m , if w...
