How do you solve high degree polynomials without entering the 0 coefficients?

-> COS(*([9 1/5 PI]) ?

"*([9 1/5 pi])" is "9*1/5*pi" in prefix notation, which is displayed if the "Simplify" CAS Setting is "None". It is displayed correctly if you either press the [simplify] button, or change the "Simplify" setting to either "Minimum" or "Maximum".
