Hi! Total noob to programming here. I am trying to solve this problem and I am stuck on a line of code. I will bold this line so it can be seen more easily. It is the exponent at the end that I believe is the problem. I am getting the error message: expected ')' before ';' token The calibration for…

I'm trying to cube a3(LogRt). I was told by a tutor to write a3(LogRt)^3 but I don't believe that is correct...

I think I got it! Thank you!!! T = ( 1/(a1 + a2log10(Rt) ) + a3pow(log10(Rt),3) ); It compiled!

It may have compiled but the equation you originally gave: T= 1 / a1 + a2LogRt + a3(LogRt)^3 and what you have in your code: T = ( 1/(a1 + a2*log10(Rt) ) + a3*pow(log10(Rt),3) ); aren't calculating the same thing. In the first one you have 1/a1 but in the second you have 1/(a1 + a2*log10(Rt)). …

emily25: T = ( 1/(a1 + a2log10(Rt) ) + a3pow(log10(Rt),3) ); It compiled! It compiled, but your answer is wrong. Or your transcription of your homework problem is wrong.

What happens if you let the compiler know to do everything in floating point arithmetic by adding decimal places? T = ( 1.0 /( a1 + a2*log10(Rt) + a3*pow(log10(Rt), 3.0) ));

econjack: What happens if you let the compiler know to do everything in floating point arithmetic by adding decimal places? Your compiler will be doing everthing in floating point anyway. Values in aritmetic expressions get "promoted" to double if either operand is a double. So the division will…

You seem to be asking how to calculate n to the third, right? While pow() can work, it is a wasteful function for calculating n * n * n.
