I have first mode shape values according to the beam length.
beam length mode shape value
0 -0.000230888
0.3 0.167612145
0.6 0.355166168
0.9 0.497419808
1.2 0.54998773
1.5 0.497419808
1.8 0.355166168
2.1 0.167612145
2.4 -0.000230888

I want to get second derivative of this curve. Please help me, this is very urgent.

You asked this same question the other day, to
which I offered several suggestions. Clearly your
homework is due tomorrow morning, as this is
Sunday evening.
