e for 4) and 5) is the exponent
How do you do the following rate of change questions
when t = 1.2 for all the following questions:
1) y = 4/t + 4lnt
2) x = sin(t^2 +1) , y = cos(2t -3)
3) x = 1 / 1+2t , y = t / 1+t
4) q = 2e^-t/2.cos2t
5) x = e^2t.t^3(2-t)^4
Please could you explain the process as im quite lost. Thanks
