10.2.6 Simplifying trigonometric expressions
The trigsimplify
command simplifies trigonometric expressions
by combining simplify (see Section 10.1.3),
texpand (see Section 10.4.1), tlin (see
Section 10.2.2), tcollect (see Section 10.2.4),
trigsin (see Section 10.2.23), trigcos (see
Section 10.2.24) and trigtan (see
Section 10.2.25) commands in a certain order.
-
trigsimplify takes
expr, an argument containing trigonometric functions.
- trigsimplify(expr) returns the
simplified form of expr.
Examples
| trigsimplify((sin(x+y)-sin(x-y))/(cos(x+y)+cos(x-y))) |
| trigsimplify(1-1/4*sin(2a)^2-sin(b)^2-cos(a)^4) |
