sinh
Hyperbolic sine
Syntax
Description
Examples
Create a vector and calculate the hyperbolic sine of each value.
X = [0 pi 2*pi 3*pi]; Y = sinh(X)
Y = 1×4
103 ×
0 0.0115 0.2677 6.1958
Plot the hyperbolic sine over the domain .
x = -5:0.01:5;
y = sinh(x);
plot(x,y)
grid on
The hyperbolic sine satisfies the identity . In other words, is half the difference of the functions and . Verify this by plotting the functions.
Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of sinh(x)
, exp(x)
, and exp(-x)
. As expected, the sinh
curve is positive where exp(x)
is large, and negative where exp(-x)
is large.
x = -3:0.25:3; y1 = sinh(x); y2 = exp(x); y3 = exp(-x); plot(x,y1,x,y2,x,y3) grid on legend('sinh(x)','exp(x)','exp(-x)','Location','bestoutside')

Version History
Introduced before R2006aThe sinh
function can calculate on all variables within a table or
timetable without indexing to access those variables. All variables must have data types
that support the calculation. For more information, see Direct Calculations on Tables and Timetables.
