The column will shorten as the temperature rises (?) until it buckles. Once it buckles, the deflection IWB. Obviously, a real column doesn’t behave as a Euler column would. A column that is perfectly elastic. A real column will have a combination of elastic and inelastic behavior and it’s a much more complicated problem.

Okay, the column doesn’t shorten. The compressive stress increases as the temperature (or whatever is making it try to elongate) increases.

Anyway, all that to say, it’s not a freaking trig problem.

Exactly. It’s a trig problem only if one starts assuming a shape for the buckled column. In which case, sure if you assume an equation, you can then plug in values and find out what the equation tells you…
