What have you tried so far and what has not worked?
Are you familiar with the method you are intended to use?
What is causing you headache about these exercises?
Post some work and IŽll help...
1.I need to evaluate (x+x^3)dx with limits 2 and 1
ii. estimate the above integral using the trapezium rule using 5 strips
2.i need to use the trapezium rule with 4 strips to estimate root(1+x^2) with limits of 4 and 0
3.the gradient function is dy/dx= 1/x^2 - xrootx
4.I need to find the stationary point of the graph y= (1/x) + (1/x^2) - (1/x^3) and need to determine their natures of each
I need help with these 4 please. Dont think you have to answer them all, but i do need all the answers and working out Thanks
