Find the gradient of a curve whose parametric equations are x=t^2/2+1 and y=t/4-1 when t=2

Remember that the gradient of a curve is expressed as dy/dx. This can be solved by using the chain rule: dy/dx = dy/dt*dt/dx. The dt in the denominator of the first term, and the numerator of the second term...
