Hello, everyone.
Please, refer me to a correct mailing list if this one is not
appropriate,
I am trying to make calc apply the most basic trigonometric identity,
and simplify the algebraic formula "sin(x)^2 + cos(x)^2" to 1.
I tried 'a v', 'a "', '=', 'j D', 'j M', but seemingly, all in vain,
even though "sin(x)^2 + cos(x)^2 = 1" seems to be one of the safest
substitutions in algebra. (Not sure about 'x having a quaternion value,
or working in some arithmetic mod p.)
What am I doing wrong?
