The question tells us the ratio between two algebraic expressions is the same as the ratio between 2 other algebraic expressions. So, we can re-write the equation as (2x-1)/(x-4) = (16x+1)/(2x-1)Re-arrang...

The surreal image of this place aids the clear portrayal of excessive wealth, prominent throughout, which is closely linked to the worshipping of luxury. For example, the "large, proud, rose-coloured...

Nerve impulses travel in one direction from the pre-synaptic to the post-synaptic neuron across a gap called a synapse. This is done to continue a nerve impulse so that it can reach its destination in the...

Start by differentiating x² – 3xy – 4y² + 64 = 0 with respect to x to obtain an equation in x, y and dy/dx:
2x – 3y – 3x.dy/dx – 8y.dy/dx = 0 [use the product rule to differe...

As we are integrating, we must decide which method to use. As the integrand is of the form f(x)*g(x), integration by parts seems to make sense. Firstly, let L = INT(sin(x)*e^x). So we want to find L - thi...
