Solution: Parametric Differentiation with utilisation of Chain Rule.By the chain rule: dy/dx = dy/dt * dt/dxNote: dt/dx = 1 / (dx/dt)So dy/dt = 0, dx/dt = 3at^2So dy/dx = 0 * 1/(3a...
You can solve a cubic by applying factor theorem. This is where you plug different values for x into your cubic f(x) = ax^3 + bx^2 + cx + d such that x is a factor of d, until you find a value t for which...
This question requires integration since the area under the curve is equal to the integral between these bounds. Initially let u=3x-2 and differentiate with respect to x so then du/dx = 3. Rearrange to dx...
First, you have to work out the values of t1 and t2 at which the particle is at rest. This is done by solving the quadratic equation for v, producing values for t of 13/8 +- sqrt(137): 0.1619s and 3.088s....
dy/dx = 6x2 - 3x + 4To retrieve the original function y from dy/dx you have to integrate the derivative with respect to x.y = ∫(dy/dx)dxy = ∫(6x2 - 3x + 4)dxTo inte...
