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)
