You can modify the parameters a and b to create new identities. Subtraction formula: replace b with -b Double-angle formula: replace b with a Half-angle formula: replace and solve Start with the double-angle formula and solve for sin(a), which is half the angle used in sin(2a...
Hyperbolic Trig Identities Solved Problems Lesson Summary Frequently Asked Questions What is cosh and sinh? Cosh(x) and sinh(x) are the base hyperbolic trig functions. They are similar to cos(x) and sin(x) except they relate an area in a hyperbola to an x or y coordinate instead of re...
