Hi, How do you differentiate the following equation with respect to x?
E = 1/2mv^2 + 1/2*2kx^2 + 1/2*3k(xb-xa)^2
ignore the b and a after the last set of x's - this is just to say the will take on different values.
Is this what you want to differentiate?
Do you understand the power rule of derivatives? If not, you should review the rule. I posted it here: http://www.mathhelpforum.com/math-he...78-post56.html
