Abstract / Description of output

We explore uses of a link we have constructed between the KeYmaera hybrid systems theorem prover and the MetiTarski proof en- gine for problems involving special functions such as sin, cos, exp, etc. Transcendental functions arise in the specification of hybrid systems and often occur in the solutions of the differential equations that govern how the states of hybrid systems evolve over time. To date, formulas ex- changed between KeYmaera and external tools have involved polynomi- als over the reals, but not transcendental functions, chiefly because of the lack of tools capable of proving such goals.
