INPUTS - WHAT TO TYPE IN

Enter your function and compute if that function is a valid capitalization or discounting function.

How to write a proper function:

• \(2t+5 \;\Rightarrow \;\) 2*t+5
• \( \frac{1}{1+t} \;\Rightarrow \;\) 1/(1+t)
• \(t^2 \;\Rightarrow \;\) t^2
• \(t^{-2} \;\Rightarrow \;\) t^(-2)
• \((1+ir)^{t+1} \;\Rightarrow \;\) (1+ir)^(t+1)
• \( \sqrt{1+t} \;\Rightarrow \;\) (1+t)^(1/2)
• \( e^{-0.2t} \;\Rightarrow \;\) exp(-0.2*t)
