Hi all,
I'm still pretty new using SageMath, but I'm trying to duplicate functionality that I've been able to do in wolfram alpha
Wolfram Input:
Intersection points of [//math:90000 1.03^x//] and [//math:63000 1.095^x//]
So far I've been able to recreate and graph these functions very easily using SageMath, but I'm having a difficult time using the solve function to actually return a numerical value for the intersection point itself.
My SageMath code looks like:
x = var('x')
f1 = (63000*((1.095)^x))
f2 = (90000*((1.03)^x))
ans=solve(f2==f1,x)
print ans
print n(ans[0].rhs())
ans prints as "[ 219^x == 1/35200^(x - 1)103^x*100^(-x + 2) ]"
And I get an error "TypeError: cannot evaluate symbolic expression numerically" in my attempts to resolve it to an approximate number.
Can anyone tell me what I'm doing wrong?
