Are trigonometry and algebra 2 the same?
No, not even close. Though both work with variables in some instances and other mathematical techniques, such as logarithms and algebraic manipulation, algebra is mostly equation solving to get the variables value, though trig has equations, while trig is the study of triangular and circular measurement and using these measurements to solve specific problems. Trig is much about identities, functions and many formulas while algebra is mostly about function and equation manipulation. Still, they are both mathematical disciplines.
