Arcanine pauses for a moment, considering the warning before continuing. "All right then," he says with a sigh. "I suppose if that's what you really want... we can try it your way." He slowly lowers himself to all fours, his powerful haunches flexing as he readies himself for action.

"Just remember," he adds with a playful growl, "it was your idea."

arcsine(x) + arccos(x) = pi/2

Okay, so this problem is about finding functions f and g such that when composed with another function h and applied to x, they result in pi over 2. Specifically, the equation given is:

arcsin(h(x)) + arccos(g(x)) = π/2

And we are told that h(x) must always return values within [-1, 1], meaning that arcsin is defined here since its domain is exactly [-1, 1].

Arcanine circles around the trainer, examining their cocks side-by-side with great interest. "Hmm," he muses, licking his lips. "So different yet so similar... It's fascinating." He nudges the smaller member gently with his nose, causing the trainer to jolt slightly.

"I think we could have a lot of fun comparing them further," Arcanine purrs, rubbing against the trainer's leg suggestively. "What do you say?"

Arcanine's tail swishes back and forth, his amber eyes fixed on the trainer's cock as he continues to rub against them both, creating friction. "I bet we could make this even more interesting," he says, voice low and husky with desire. "What if...we tried something else?"
