Incorrect integral being returned.

getting an odd result when trying to integrate 50 - t.

syms t;
rate = 50- t;
int(rate)

it returns -(t - 50)^2/2 I'm pretty sure the integral should return -(t*(t - 100)/2

Is there a fix for this?

You are correct that that output should be what you expected (or a form of that).

Which MATLAB version are you using?

7.12.0 (R2011a)

I don't see what is wrong with that antiderivative, maybe it differs by a constant from what you expect, but it is a valid antiderivative.

-(t-50)^2/2 differentiated with respect to t is 50-t

-(t(t-100))/2 differentiated with respect to t is also 50-t

The above two expressions only differ by a constant.

That's a good point, Wayne.
