Tangent Calculator | tan(x)
https://numberbau.com/calc/math/tangentcalculator.htmlTo calculate tan(x) from a right-angled triangle, the formula used is; $$tan\, x = {opposite \over adjacent}$$ The tan of an angle x can also be easily determined if sin(x) and cos(x) are known. $$tan\, x\, =\, {sin \,x \over cos \,x} $$ Unlike sin(x) and cos(x), there is no well-known Taylor series approximation for tan(x).
