(math based) Computer programming, bisection method:

IN PYTHON: Use the Bisection Method to find the root to eight correct decimal places.
f(x)= ln(x) + x^2 -3.

Having trouble coming up with the program. Tried to use ln(1) and ln(0.25) .
Should be something similar to:
-----------------------------------------------------------------------------------------
from math import log (must check the command)
i=0.25
j= 1  
f= lambda x: np.log(x) +x^2 - 3 (program fails here)
while True:

k=(i+j)/2
print (k)
if f(k) < 0
i=k
if f(k) >0
j=k
if abs(f(k)) < 0.000000001:
print (k)
print (f(k))
break

Explanation / Answer

If you are getting the below error in Line 4

unsupported operand type(s) for ^: 'float' and 'int'

Use ** instead of ^ and no need to mention np.log since you have already imported log function in the import statement

f= lambda x: log(x) +x**2 - 3
