sorting - Ordering the following from smallest to largest in terms of efficiency -
i have tried sort out smallest largest in terms of efficiency got wrong.
any please?
xe, ex, (x+sinx)x20, xe, ln2x, xlnx, x + sinx, 13 + 1/x, lgx, 1/x
could define efficiency? want know how sort these regarding asymptotic complexity? link
when x grow big:
- 1/x near 0
- 13 + 1/x near 13
- lgx grow slow, lg(10000000000) = bit more 33)
- ln²x slow also, ln²(10000000000) = 530
- x + sinx approximatively x when x big
- xlnx
- x^e x^2.71828
- (x+sinx)x^20 = x^21 + x^20*sinx, si equal x^21
- e^x fast growing function, e^20 4.85*10^8
if so, 1/x < 13 + 1/x < lgx < ln²x < x + sinx < xlnx < x^e < (x+sinx)x^20 < e^x
