hyperbolic trig functions造句

Is there an inverted concept to spherical geometry in Hyberbolic spaces ( and this is * not * as far as I can tell related to the Hyperbolic trig functions ) talk ) 12 : 47, 7 September 2012 ( UTC)
An unusual feature of the SR-50 was that its functions included the hyperbolic trig functions sinh, cosh, and tanh and their inverses, which were found on very few calculators ( including the HP-35 and HP-45 ) at the time.
The SR-50 followed the standard order of operations by performing unary ( single-argument ) operations ( reciprocal, square, square root, log, trig and hyperbolic trig functions ) immediately, and multiplication, division, root, and power operations before addition and subtraction operations.
It's difficult to find hyperbolic trig functions in a sentence. 用hyperbolic trig functions造句挺难的
