RE: HP-9100A the first ?
Even earlier the 5 ton behemoth Automatic Sequence Controlled Calculator (ASCC) or Harvard Mark I (1944) however it did not have a keyboard, input came from punch cards and paper tape and output was printed on a modified electric typewriter or punched into cards. Later IBM built the Selective Sequence Electronic Calculator (SSEC) (1948) which used many more electronic circuits than ASCC, the SSEC is reputed to have been able to handle more complex math than ENIAC. Both of these machines did transcendental functions using lookup tables.

In theory any computing machinery could do transcendental functions, the only difference is it is a program calling the function instead of the function being invoked by pressing a key.
