Trigonometric identities are trigonometric equations that are always true.
"Trigonometry" comes from the Greek words trigonon and metron, and roughly translates to "the measurement of angles".
csc(x) = 1/sin(x) = +/- 1/sqrt(1-cos^2(x))
It is a number - in trigonometry or elsewhere.
how can trigonometry use in metallurgy
Trigonometry is used effectively in electronics.
An identity is like an equation which is true for all values of the variable.
I suggest that it is (sin A)^2 + (cos A)^2 = 1
