Mathematics, particularly trigonometry is one of the school subjects that very few students like and succeed at, and which most students hate and struggle with. Trigonometry is an area of mathematics that students believe to be particularly difficult and abstract compared with the other subjects of mathematics.

There's no prerequisite to learn trig first, and forcing people to learn trig-calc excites many mathophiles but is a major turn off to other students. Calculus can be taught using just basic algebra, and most students will benefit from already understanding calculus, when they are learning trigonometry.
